Badass. Also can you provide a link or resource to where you got that ratchet with flex head and the extending handle? I have one made by husky; best ratchet ever. But I can't seem to find them now. I had two one broke and down to one now.
On the LBZ, should delete factory fuel filter when adding a lift pump. The priming pumps will leak once you add positive pressure from a lift pump. Save the headache and delete. I agree with this video!
As an LB7 owner, you can under how reluctant I am to remove any filter. I literally just rebuilt my filter head 2 days ago. I've had a lift pump since 2017 after doing the injectors myself the first time. I'll keep 2 girl filters and 2 water separators. Still going strong.
I just added the Air Dog to my 2010 LMM this past weekend. Your videos were very helpful with that. Later this summer, when the engine bay filter is closer to needing replacement, I will very likely just remove the filter housing as you have shown here.
You could always get the PPE CP3 inlet upgrade kit with fuel line quick connects and eliminate the stock filter housing as well as the restrictive fuel pressure port all together and run it straight to the quick connect fuel lines on the driver side 🤷🏼♂️
This is EXACTLY what I was looking for... The ins and outs.. preferences and why Yu ou would do it. Thanks Josh for the quick and informative videos.. your on target for your audience..
Not to be rude but your not getting any more filtration with 2 fuel filters. I had bad experience with cat. About 1/4 tank or a lil less. I would lose fuel pressure an trk would shut down. But i had those huge cat filters. Now i only use AC delco or baldwin. Which ever is on sale. Lol.
@@lancewilliams3396 I’ve never had a problem, with mine , but my lift pump is a bully dog not a fass , maybe that has something to do with it ? not quite sure, but I’ve been running it that way for years, I live up in Canada and the weather gets pretty darn cold up here and still hasn’t had a problem
Did the Air Dog pump on mine JUST before an injector went bad.Removed the stock filter and housing too.Simplifies engine bay for future repairs.Plus,I'm told if still using a CP4 as I am the lift pump is a must have.I got an insurance policy for the pump,and maybe a week later an injector failed.Awesome luck I have.
I have a 100gph airdogg for my lb7. I also have the cat filter adapter in the engine bay. The engine bay fuel filter gives me some more peace of mind knowing those fuel lines running back to the lift pump will not release any rust that would reach my injection pump or injectors.
If you want to eliminate the filter use the blocker plate as the factory filter housing also has a heating element in it for colder climates, and even with winter diesel on especially cold days this could leave you stranded on startups as the fuel will not flow properly. And if you are running a multi system filter setup with lift pump then you won't need to change the filter as much, but with the factory filter in place it will also give you a warning if you get a bad batch of fuel with high water content and hopefully prevent you from blowing the tips off your injectors due to water.
Great job on showing what to do and why you did it, I’ll be watching every video. I just picked up a 83,000 mile LLY truck , hopefully some of this will work on it Terry
Bro go back to some of TM older vids. His mods and repairs to his LBZ are dam near identical to your an mine LLY. His vids helped me out a great deal. Get rid of the stock mouth peice. Cheapest route is replacing it with a LBZ mouth peice. Then replace fuel pressure valve with a PPE. Spring in stick one gets real weak due to time and mileage.
I drive a 15.5' lml w/ fass 165 lift pump. I'm not deleting the stock filter until I get my cp3 conversion done, just saying... I do have a wcfab fuel system saver inlet metering valve for now tho. 🇺🇸
Very good video. My fuel filter housing left me stranded 8 hours from home and i couldn't figure out why the truck wouldnt keep running. It had a hairline crack in it. Replaced it with a new ac delco and it leaked aswell. Deleted it and havent had one issue since
Not true. Been running my truck this way for over 10 years. They still need replacing and they do get dirty, but not as bad. It never hurts to have a last chance filter to save your injectors from contaminated fuel. It is done on diesel boats all the time.
Removing your filter for your daily driver is just asking for injector issues down the road from the dirty diesel they sell these days ! I double or even triple filters, it’s not going restrict any flow what’s so ever ! Filters are cheaper than injectors.. Just my two cents 🤷♂️👍🏻
Like the recent videos - this one is same as my truck (2008 Chevrolet 2500HD crew cab w/ short bed) so extra helpful. I'm currently replacing all the fuel hoses w/ braided stainless steel due to flexing in the rubber parts of the originals - was getting fuel starved and giving code P0087 then limp mode. Pulled the tank, changed the sending unit, changed all the supply /return lines. Still have to do the 5 little ones under the hood (269.00 for 5 little hoses) FYI - If you run into a decent set of stock exhaust manifolds with heat shield for the LMM I would be interested - mine are about rusted away. Like the vids - keep it up
the issue with removing the factory filter and filter head, is if u do get water in the fuel and you dont have the factory filter and sensor there, you will not know and it will destroy the fuel system, that is why i just leave it there for the WIF sensor... its cheep insurance, yes the air dogs filter can hold alot of water, but usally when u get water in the fuel you get 2 or 3 liters in there, which will fill that filter quickly.
On the lly i ran my line that would goto the filter from the ficm right to the line that connects to the Schrader. It has enough bend to work perfect. Runs right up the side of the ficm to that connection.
Very interested in this build as I have a 2008 GMC 2500hd. It came with an Air Dog lift already on it. Looking to put Kryptonite steering components and a larger fuel tank on it.
I’m old school and the lift pumps ant all they are cut out to be they cost a lot of money versus the standard housing and if the motor ever goes out on your lift pump your stranded as well and we are talking close to a thousand dollars a piece for one versus I can buy like for OEM factory housing with the filter for around 170 a peace from the manufacturer.
On my LB7 2001 there’s a wire that goes from the bottom of the fuel filter housing to the harness. Maybe a sensor wire that connects to an idiot light. If bypassing the housing is the loose wire going to work the dummy light? If not, there’s a bypass bowl that allows one to reuse the drain where the sensor wire connects. I wonder if the dummy light will sense this modification
Yes delete it because the positive pressure from the lift pump blows by the orings in the filter head and will cause a leak. I rebuilt mine 3 times before I just yanked it out. Haven’t had a issue since.
I'm have trouble starting my lml have a 165 on it I here the pump running but just truns over think it might be pulling air some where I can get it start with a shot of starter fluid and she will run was trying to see if maybe I needed to do the same and delet the housing ?
I just installed my AD165 in my lml and was gonna just let my fuel filter get to the end of its life then I’ll delete the housing less crap in the engine bay the better
I personally run 3 filters on my 01 LB7. I only do it cos I’ve spent upwards of 7500$ on fuel system components. And these aren’t even performance components. Injectors, CP3 and lift pump. I really don’t want to replace them again.
Sorry in advance for the long post. I put an airdog lift pump on my lly, thought to myself "wow, its running way smoother". But I had to fill up a little sooner than usual, later that same day I found I had a fuel leak, the factory filter housing had a leak at the primer button. Ended up bypassing the factory filter. Can only wonder how long it was leaking, or if the lift pump caused it to start leaking.
Josh, will the 1/2 in hose that comes with the air dog lift pump be adequate tubing for this delete. I just crawled out from installing mine on my 15 lml and wanted to use the leftover hose if it was possible Thanks
Nothing hurting them injectors after the aitdog165 or any of them no need for the extra imo.but i no why u saidwat u did ...ive done 10plus trucks all brands same way ovr 7years.not 1 problem all rates are still perfect
@@truckmastergarage9944 I am impressed u got the turbo outta there like that I worked on my share of dmaxs the last 5 years and myself ain't removing it without the cab off
I just installed a air dog 165 on my 2013 duramax. The fuel filter housing started leaking so I rebuilt the housing and got a new fuel filter. It is still leaking!!!! Would you recommend me doing this to my truck? Is there a place to buy a U shaped fuel hose? Thank you for you help. Love your channel.
Filters there for a reason protects the injectors lol but I mean if 50 doller filter is expensive to you then wait till the injectors go from dirty fuel that 50$ is far cheaper
I've had my lb7 since 2016. I was the only one that worked on it until 2019 and until then it ran like a champ. Now because I trusted that others knew more than me about my diesel it's been in limp mode for so long I'm afraid it's going to go down in flames while I'm driving it. You tube served me well until someone did so much on it I don't know where to start. Wish someone around here knew anything about duramax. If only I'd of stayed single....I think he was only with me for my truck. Until he broke it. I got a lincoln 2011 running great when no one else could then some dude stole it from me. Can't a girl love tools and trucks and mechanical stuff without a guy wanting to take it all away? Well you can't keep this girl down. I have 99 problems I hope my injectors arent one. I'm gonna hide in a shop somewhere until I figure it out. Bury me with my tools if it kills me trying.
love your videos man but if the stock filter is still getting dirty and needs replacing, then in my mind there is something left to be desired filtering wise with the pump??! ive ran my Fass 150 on my LBZ along with the cat under hood filter the last 100K with no issues. This spring when i replaced all of my fuel filters approximately 15K on em, the cat filter was dirty a bit, not bad by any means but definitely not new. My kanundrum is, if the lift pump whatever brand it is Fass/Airdog sends entirely clean fuel to the rail then why does the factory filter still need to be changed, there should be absolutely nothing getting caught in it anyway, which that definitely isn't the case. so by deleting the factory filter, where is all of this still factory filter caught material going and going through?? Hmmm...
@@truckmastergarage9944 ha i usually end up doing two fuel filter changes to one oil change if ya get what im sayin, an fuel filters are usually done around 10-18K.
I gotta question If the stock filter is no longer needed . That must mean its not filtering anything out of the fuel , im assuming. So , why would i have to change the filter , incurring the extra costs, you mentioned. Because if it is clogging up , even over a long period of time , thats a good thing , thats its catching , anything that gets passed the fass fuel system ,dont you think ? Plus How do you prime , without that plunger ontop of the stock filter mount ? I do like the extra room though . Also , do you know if anyone has tested the fuel flow rates , comparing the two ? ( with fuel filter delete compared to leaving factory filter system in along with the fass fuel system) Ok Thanks
So what happens if your lift pump goes out and you need to bypass the lift pump back to stock to get the truck going again....but you have no filter???
@@truckmastergarage9944 there are no filters at this point. Your lift pump has failed, you have removed and bypassed the factory filter, so now the CP3 is pulling straight fuel from the tank to your injection system. I get the whole bypassing the factory filter and it being less restrictive but seems smarter to keep it there and replace the factory filter less often since there should be clean uncontaminated diesel fuel running through it. Just my two cent...
@@truckmastergarage9944 is the FASS also designed to flow open after failure? I’ve seen in previous comments where you mention blocking the intake to choke the system for priming, is that option still possible with a failed lift pump? My concern would be getting stuck in the woods with no alternative priming method if lift pump crapped out
Love your videos, however I have a 2006 LLY GMC SAVANA! Things are not the same! I bought it modified and I’m the third owner, I think I have two fuel filters, one in the engine bay and one up underneath! The one in the engine area is impossible to get to, I want to replace it but I’m not sure if it’s a standard size?
In another video you said the only way you'd run a FASS pump is if you used different filters. I have an LB7 with a FASS, it came with it when i bought the truck. I was just wondering what filters you would recommend for the FASS pump?
I just had a mechanic, do a fuel pump conversion, and a push pump on a 2016 and when I got it back, it was sluggish and surging in places. What did he do wrong?
I'm have trouble starting my lml have a 165 on it I here the pump running but just truns over think it might be pulling air some where I can get it start with a shot of starter fluid and she will run was trying to see if maybe I needed to do the same and delet the housing ?
I have a 2014 been going back and forth with the idea of a air dog pump or just the cat lift pump you installed on the wifemax. And advice would be appreciated
I have an LB7. And the FICM went out due to my mistake. But after replacing it. It’s leaking diesel near it. Can’t tell what’s actually leaking. Nothing leaked before module went out. Are all the fuel lines 1/2”?
Im about to install the AirDog 165 on my 2012 LML (better late than never I guess) but I chose to go with the fuel filter delete kit. Basically puts a shorter, pass thru filter in place of the factory filter. I had never considered completely removing the filter housing and bypassing with a hose like you did here... I like the idea, but I already paid for the delete filter and am out of the return policy haha. Any reason why I should do this over the delete kit?
I have an 11 LML with the FASS delete kit as well as Fleece priming bulb delete since I have a FASS 165 lift pump. I just purchased the little U shaped hose kit and will be removing just because I want to get rid of as much unnecessary parts as I can.
Maybe I just effed up? Lol. I had cp3 conversion I installed on my 15’ lml, got rid of the oem fuel filter housing but did away with the pressure relief valve as well? I understand that might. It be ideal, but should still work, correct?
I got a question I have a 2009 chevy silverado 2500hd duramax 4wd stock 156k miles runs and drives great but when i pull a dump trailer it over heat i already install a mishimoto radiator and still the same i wanna know if you have any suggestions?thank you very much
I'm try to fix my lb7. This is the second time for head gaskets. What do you thank the best gasket is to use. Would it be beneficial to use the screw in cups? This is very frustrating. I had a shop do the head gaskets before. It's only been about 20000 miles. If I replace them again is this going to be a constant issuem
So is there still a way to prime your fuel system once removing the filter housing? I'm asking because I recently ran out of fuel and couldn't get it to start until I primed it with that button on top of the housing. I have a lift pump as well
Josh dude when you made that RC bumper and installed it on your LMM you completely blocked the air flow to the transmission cooler, for the cooled transmission fluid with that bumper.
Does deleting the stock filter make a difference in a return flow rate test? I already have an airdog installed. I need a test done to check out my injectors.
I plan on doing this once I do upgrades to my lmm and whole make over next spring, hope to start my channel on it as well. Anyway. My question is. Since it’s unplugged would it throw codes? 🤷🏽♂️
I just followed your video step by step, and I went to start the vehicle and it started but died instantly. My CTS3 is showing that my fuel rail pressure isn’t meeting the desired to start the truck. I’m not hearing my lift pump turn on when turing the ignition on. Any info on why this might be happening would be greatly appreciated.
I recently built my lly duramax rds 68mm, dual fuelers, 75 over injectors, 150gph lift pump, ARP head studs, up pipes, down pipe, 5”exhaust and all the HSP piping. It made 570whp in tune 3 out of 5. Haven’t had a chance to try tune 4 or 5 cause it keeps going into limp mode throwing a low fuel rail pressure code. Any idea what could be going on?
What do you guys think about the new install channel?
Digging it! Love the short AND useful videos!

The OEM filter is supposedly 10 micron. With lift pumps having smaller than that, theoretically, OEM would never get dirty, and never need replacing.

Because if it is clogging up , even over a long period of time , thats a good thing , thats its catching , anything that gets passed the fass fuel system ,dont you think ?
Plus
How do you prime , without that plunger ontop of the stock filter mount ?
I do like the extra room though .
Also , do you know if anyone has tested the fuel flow rates , comparing the two ? ( with fuel filter delete compared to leaving factory filter system in along with the fass fuel system)
Ok
Thanks
Truck masters bicep is looking jacked in the thumb nail! You hitting the gym???
😂 no just turning wrenches 🔧
I did the same
Good video!!!
Left me stranded had to delete it on the side of the road on my lbz I need to delete it on my lb7 so it doesn't do the same thing
And if you need to bleed the system, how do you do it if the primer bulb is removed?
Just did the delete as well. Truck fired up then quit. Now just turns over but won’t fire. Not sure what to do now.
So what happens if your lift pump goes out and you need to bypass the lift pump back to stock to get the truck going again....but you have no filter???
Truck will still run and filters will still do there job but the cp3 will work a little harder. It’s really not that big of a deal though
@@truckmastergarage9944 there are no filters at this point. Your lift pump has failed, you have removed and bypassed the factory filter, so now the CP3 is pulling straight fuel from the tank to your injection system. I get the whole bypassing the factory filter and it being less restrictive but seems smarter to keep it there and replace the factory filter less often since there should be clean uncontaminated diesel fuel running through it. Just my two cent...
Great point however the Airdog pump motor is designed to flow open if the pump fails so it will not leave you stranded
@@truckmastergarage9944 is the FASS also designed to flow open after failure? I’ve seen in previous comments where you mention blocking the intake to choke the system for priming, is that option still possible with a failed lift pump? My concern would be getting stuck in the woods with no alternative priming method if lift pump crapped out
I have a 2020 Chevy 6.6 turbo diesel should I change the fuel filters and
Love your videos, however I have a 2006 LLY GMC SAVANA! Things are not the same! I bought it modified and I’m the third owner, I think I have two fuel filters, one in the engine bay and one up underneath! The one in the engine area is impossible to get to, I want to replace it but I’m not sure if it’s a standard size?
How do I prime to build pressure??
Cycle the key in the ignition appropriately 30 seconds each duration
In another video you said the only way you'd run a FASS pump is if you used different filters. I have an LB7 with a FASS, it came with it when i bought the truck. I was just wondering what filters you would recommend for the FASS pump?
I just had a mechanic, do a fuel pump conversion, and a push pump on a 2016 and when I got it back, it was sluggish and surging in places. What did he do wrong?
Great videos
I'm have trouble starting my lml have a 165 on it I here the pump running but just truns over think it might be pulling air some where I can get it start with a shot of starter fluid and she will run was trying to see if maybe I needed to do the same and delet the housing ?
How do you get air out of the lines to get fuel pressure
I have a 2014 been going back and forth with the idea of a air dog pump or just the cat lift pump you installed on the wifemax. And advice would be appreciated
Does disconnecting the WIF sensor cause a message on the DIC?
I have an LB7. And the FICM went out due to my mistake. But after replacing it. It’s leaking diesel near it. Can’t tell what’s actually leaking. Nothing leaked before module went out. Are all the fuel lines 1/2”?
What about the water in fuel sensor won’t you get a check engine light if you unplug it? Just curious
It should through a code but I never had a check engine pop up doing this
So without the housing how would you go about priming?
What about the fuel heater that your removing?
There is no need for it
Im about to install the AirDog 165 on my 2012 LML (better late than never I guess) but I chose to go with the fuel filter delete kit. Basically puts a shorter, pass thru filter in place of the factory filter. I had never considered completely removing the filter housing and bypassing with a hose like you did here... I like the idea, but I already paid for the delete filter and am out of the return policy haha. Any reason why I should do this over the delete kit?
I have an 11 LML with the FASS delete kit as well as Fleece priming bulb delete since I have a FASS 165 lift pump. I just purchased the little U shaped hose kit and will be removing just because I want to get rid of as much unnecessary parts as I can.
Maybe I just effed up? Lol. I had cp3 conversion I installed on my 15’ lml, got rid of the oem fuel filter housing but did away with the pressure relief valve as well? I understand that might. It be ideal, but should still work, correct?
Might not*
Did it take long to purge the air out the line.
I got a question I have a 2009 chevy silverado 2500hd duramax 4wd stock 156k miles runs and drives great but when i pull a dump trailer it over heat i already install a mishimoto radiator and still the same i wanna know if you have any suggestions?thank you very much
I'm try to fix my lb7.
This is the second time for head gaskets.
What do you thank the best gasket is to use.
Would it be beneficial to use the screw in cups?
This is very frustrating. I had a shop do the head gaskets before. It's only been about 20000 miles.
If I replace them again is this going to be a constant issuem
So is there still a way to prime your fuel system once removing the filter housing? I'm asking because I recently ran out of fuel and couldn't get it to start until I primed it with that button on top of the housing. I have a lift pump as well
Block the intake and have a buddy turn the key to choke the engine until it starts 👍
Thanks for the reply. I will give it a try next time! Love watching your videos
@Zack Oberle Did the choking work for you, Zack?
If you were buying a 14 duramax. Would you make the dealer replace the cp4?
If I put a lift pump in my truck would that affect the warranty I have a 2020 Duramax high country
Ok, but what about loss of the fuel heater?
Josh dude when you made that RC bumper and installed it on your LMM you completely blocked the air flow to the transmission cooler, for the cooled transmission fluid with that bumper.
How would you prime the fuel system?
I did the fuel filter delete like the video now I’m getting a crank no start what did I do wrong? 😢
Does deleting the stock filter make a difference in a return flow rate test? I already have an airdog installed. I need a test done to check out my injectors.
I plan on doing this once I do upgrades to my lmm and whole make over next spring, hope to start my channel on it as well. Anyway. My question is. Since it’s unplugged would it throw codes? 🤷🏽♂️
It’s hit or miss but normally it won’t
Sounds good, wish I could’ve went to truck meet in Wisconsin! I would’ve enjoyed getting info from you! Lol
Hopefully we can do it next year
I been planning on doing what you just are doing right now on the lmm so the videos on it are going to really help lol.
Is this the same process for a LBZ?
I just followed your video step by step, and I went to start the vehicle and it started but died instantly. My CTS3 is showing that my fuel rail pressure isn’t meeting the desired to start the truck. I’m not hearing my lift pump turn on when turing the ignition on. Any info on why this might be happening would be greatly appreciated.
what effects are there by not running the fuel through the icm? on a lb7
So what happens if you loose prime ? Or go on e
I recently built my lly duramax rds 68mm, dual fuelers, 75 over injectors, 150gph lift pump, ARP head studs, up pipes, down pipe, 5”exhaust and all the HSP piping. It made 570whp in tune 3 out of 5. Haven’t had a chance to try tune 4 or 5 cause it keeps going into limp mode throwing a low fuel rail pressure code. Any idea what could be going on?
Did you install a ppe race fuel rail plug
I was just going to ask, you might need a race plug
@@truckmastergarage9944 Shit I can’t believe I forgot that I ordered one tonight that should fix it thanks for the help
@@truckmastergarage9944 Sorry to ask another question how much power can my lly Duramax handle you think it’s completely stock bottom end
Bottom end on borrowed time would easily handle 700 but trans and top end maybe 550-600
How long did you crank on it before it started?
Do you have to remove the alternator?
