Fantastic! I was just figuring out my fuel system and this was perfect. 👌 It cleared it all up. Love the simplicity! Thanks JR!
Thanks JR, I was making my fuel system more complicated than it needed to be. This got my mind right.
Thanks for the Awesome videos, Can't get enough. The fuel press regulator's are known to leak internally sending fuel into the vacuum hose and into the intake causing idle misfire and P0300. Usually after 100k miles or so, thats why they go missing lol.
Thanks for the great info and another great video. I appreciate your work.
Great post! Definitely definitely needed to see this. I been at a standstill with the fuel swap. Thanks
Glad it helped!
Appreciate all your stuff man what a 🧠 .....
Heck yeah man thanks for the info really enjoy your content no BS just the facts I got me a 5-3 on a stand waiting on my balance to remove her to get here getting ready to cam small turbo Etc saw this info comes in very handy and it is the return Style I will definitely check those adapters out
Great video! Keep em coming! 👍
Thanks! Will do!
Looking forward to the DBW vs DBC video
I cant wait either.
I had the return type fuel rails and the corvette return type regulator. Thanks for clarifying these differences ! I'll be switching to the returnless rails and keeping the Corvette regulator.
Your info was helpful thanks 👍💪
Glad to hear it!
Thanks for the video
Very impressive, this upload...
Thanks brother, this helped me.
Glad it helped
I got those fuel rails for my tbss intake off of an 04 motor I believe. It fit fine
Save yourselves a ton and buy evil energy line I’ve used it now with no issue on a dozen or so builds and for several repairs on daily drivers.
Will the 5/16 return on the stock truck intake be big enough for the walbro 450 pump? Love the videos.
Yes, what you wind up doing is just adding pumps
Should I upgrade from truck intake to NNBS “bread box” for LQ4 wSS2 cam?
So on the 07+ intake/fuel rail can I place a regulator between the feed and the fuel rail with a return line going back to the tank?
03 yukon gas pedal.
Last thing to disconnect looks like a vacuum hose?
Goes up high behind dash?
Do I cut it?
That intro tune is Steven 'n' Seagulls band from Jyväskylä, Finland!
Love the videos, trying to figure out what to do with my fuel system if you have any suggestions, 07 suburban full exhaust, cammed with a whipple stock pump and regulator with 50lb injectors, I plan on upgrading the pump and going with 90lb injectors, would it be best to go with an external regulator with a return line?
Theres no need to unless you just think it looks cool
Thank you!
You're welcome!
I’ve got a 05 with returnless set up that needs hoses changed due to v8 swap; hose feed is kinked.
Do you recommend the return style better. Specially when going cam and turbo in near future?
Have you done a video on low Clarence intake manifolds i.e. for a 2nd. Gen. Firebird?
No, but buts a great idea!
The clip on regulator on the fuel rail is a high failure rate item and causes long starts. It also destroys its own evidence. Let it sit overnight and if you find fuel in the vacuum line that goes to it, it's bad.
The Russell quick connect with the plastic clip leaks? Hmm
My 07 6.0 from a express van was returnless and dbc
On a breadbox intake? I don't think so
Van's aren't trucks
Great video. Do you know off top of your head which returnless rail will be a direct swap onto a return style 2002 intake? I’m swapping into a flex fuel s10 and has returnless/corvette regulator setup from factory. If I could just swap the rail setup it would be optimal. Thanks for your help
A normal 02 rail is return
@@TheDrivewayEngineer right but I need a returnless rail that will mount onto my 02 intake. My s10 that I’m swapping into already has returnless fuel setup.
Hello good Video quick question would I still need a aftermarket fuel regulator or Can I just use the stock regulator on the first gen truck intake
The one on the intake is good to go
@The Driveway Engineer ok thank you
Can I cap off the return on the intake since Ima be running the return fuel filter?
Have you figured this one out yet bossman?
How do I bypass my in tank regulator? It hates my Walbro 525. Bought a aftermarket regulator and I'm just wondering if I have to block off the one in the tank by using a Corvette in tank regulator bypass, or if I have to do something else
No idea what an intank regulator looks like. But if I hadf one, I'd just take it out? Can't be that hard.
@@TheDrivewayEngineer it isn't but its spring actuated and has a ground wire running to it as well. I'm just not sure that if I take it out it'll build pressure with the regular regulator. It's built into the pump basket and fuel has to flow through it. Look up Chevy avalanche 1500 fuel pump, 2004
Will the 04-07 returnless system with the in tank fuel regulator work with a turbocharger setup.
No
I have a 2002 5.3 LM seven that I am turbo charging. I did buy the 80 pound deca injectors. What do I need to do with the factory fuel pressure regulator do I buy a bypass cap that goes on it or just unhook it and use an aftermarket fuel pressure regulator, and what kind of PSI would you recommend running on the new 80 pound injectors at the fuel pressure regulator?
No reason you can't use it exactly as is
@@TheDrivewayEngineer ok love the videos thanks so much
I've had good luck with the evil energy stuff
Second that, had no issues with mine.
I third that. Evil energy seems to be legit.
I often wondered if anyone had good luck with evil energy. They are pretty juch everywhere on Amazon
Fourth that. 1-2 years now
Hello. I am swapping a 5.3 from a 2003 suburban. It is a DBW and return style. It is getting put into a 2006 Colorado 2.8 with a returnless system. Is it as simple as blocking off the return line on the rail to make this system work?
It's simpler to just swap the rail probably
Is there a difference between the regulators with the vent tube on the side and ones with it on top? Mine has the regulator with the vent tube on the top and the vacuum line to it wont stay on due to the orientation. If that doesnt matter then ill be ordering one with the tube on the side
I've never noticed that, I've always used whatever I have
Great info! Thanks! Im putting a 2003 5.3 in my C10 in which I relocated the tank underneath the bed. The 5.3 has a return style intake and Im wondering if you think its ok to use the Corvette style filter /regulator and bypass the regulator on the fuel rail. The reason is I was hoping to avoid having to run the return line all the way to the back of the truck. Thanks
Yes, you can do that, you have to change the injectors in the tune though
Thanks for the info! I’m doing the same thing, but I’m not going to change my injectors. I’ll just run it all the way back and leave stock injectors in the motor. My retromod is a 1959 Apache sitting on a 1983 frame, with an LM7 for power.
So u can just mount the c5 filter where the stock filter goes on a return system and just make the return alot shorter? I currently have it on the tbss fuel rail and I hate it. Scared its gonna leak
No, not at all, no way.
@@TheDrivewayEngineerno way what
so building a car on a whim. guessing i got a 03 due to the design of my system. in line fuel pump, had to put a return in the tank. my question. due i run the return line from the intake to the tank? can i plug the return line port in the fuel regulator i bought. my current set up is tank-filter-pump-filter-10 feet of line to the regulator under the hood regulator to fuel rail. i currently have the return port on the regulator plugged with a bolt it cam with. so can i just run a few extra feet of return line straight to the return port on the rail?
I'm lost in all of that lol.
If you have a return rail, use it and throw the regulator out.
If you have a return less, run the return from the regulator
@@TheDrivewayEngineer well the pump can do up to 80 psi.
So the regulator drops it down to 60 psi to the rail. I'm just asking where does the return line on the rail go. Straight to the tank? I don't have the corvette style. Tank to pump pump to regulator 60 psi regulator to rail rail back to tank
@@TheDrivewayEngineer
So I had to do some looking.
I have a 07 cast iron block
With a 03 shaved and sanded intake
With a 02 throttle body.
My current options are.
Buy a new fuel rail system but idk which to buy?
Or plumb the current set up.
I could provide pictures if needed im just not well versed Here and hoping for some input from someone who knows more
99-03 style with return. Do you have an additional regulator or just the fuel rail? Thanks
Regulator on the rail is all you need
Thanks so much@@TheDrivewayEngineer
I have bosted 08 silverado 5.3. Is it best to convert to fuel return? And is there a video you know of that shows how to?
If it's working now why switch?
@TheDrivewayEngineer my fuel line in the gas tank keeps blowing off. What's a good submersible hose? I used one from gates and it started breaking down and got slimy.
I have a 2005 silverado with a non-return fuel pump system .... but I would like to know if I can convert it to return style .... I have heard that the 2005 works with a module that controls the fuel pressure ... My plan is to install a return style pump with the corvett c5 filter so the return style pump would only install the ignition current and the pipeline until there I'm fine I think ... what worries me is that the module would be disabled and I don't know if I affect the melody or operation of the truck since I do not want to use that module ... any help would be greatly appreciated
You can converter to the return style rail, just swap it, and tell your tuner.
If you want to use the Corvette regulator... Then keep the returnless rails.
@@TheDrivewayEngineer then you would have to run new wiring for the return style pump and disable the fpcm module
@@alejandroamaya5907 yep, it's one wire lol
@@TheDrivewayEngineer That wire would only be the positive wire that would turn on the fuel pump, right?
@@alejandroamaya5907 correct
I have 06 silverado 1500 4.8 I don't see a pump or pressure regulator on frame or anywhere. I'm not a mechanic. I didn't think its beyond my ability. Its a 3/8 single feed. I was gonna make fuel line out of metal and rubber. Do I need a regulator on the fuel line. The only place I cant see it is around bell housing so I am confused any help be appreciated.not Debbie her son using her.
There's no return on a 06 Silverado
Regulator is in the pump assembly in the tank
What is the advantage to cable drive vs fly by wire,
If you have a car with a cable gas pedal already in it, it's the easiest way to go
Cable response is better.
I'll discuss that in an upcoming video, but other than ease of install, the DBW is better in every way.
If u want cruise control dbw is way easier
Dbw is easier to tune from what I understand.
Do i have to be a high ass efi tank or can i use the factory tank? It currently has a external fuel pump
As long as you use a fuel pump that can keep up with required PSI.
I did a 1950 buick if you go in tank pump u will have cavation issues with a unbaffled tank u can add baffles to tank u got but its no easy I bought a efi tank for a 1953 chevy from tanks Inc's for like 300 shipped after the stock tank was a major fail depending on your vechicle u might be able to find a close enuff tank at pick a part that u can make work
@@jeremyhanna3852 72 monte , 63 nova guess ill be buying new tanks
@@tennesseesyndicate5337 yeah if there is radiator or tank shop in your area they might beable to baffle what you got cheaper than New tanks
@@tennesseesyndicate5337 i think some where I read u can reto fit a k5 blazer tank in the monte easy but not sure and u can get a efi tank for 88 k5 pretty cheap
Friend of mine got his breadbox intake running with the old style fuel rail/crossover by adding injector spacers
Kind of a hack though
I've seen people solder up different stuff as well.
Had a donor 2006 escalade with returnless system- did a 4.3 to 6.0 swap it to 2005 silverado- had same setup on fuel line and connector, do I need to upgrade anything?
Nope
Never had one leak. That was hundreds at the dealership as new o-rings came in the package. Hit with compressed air, wipe clean with rag, use pick to change. Love the channel but changing engines may have stressed a fitting and tiny micro fracture. When GM sees a high failure rate they ask dealers to ship them back to testing. Stress cracks was the only issue per hundred with cut o-ring, dirt. Not sorry. ASE Master Tech since 78. Retired.
I have no idea what you're talking about, so no need to apologize 😂
I was curious and been looking and trying to find out if I can put corvette fuel filter/regulator in tank? Vintage car with 1 fuel line. Not sure if would work hoping someone has tried it.
I suppose you could, I don't see why it wouldn't work if it fits, usually the holes in the early tanks are too small
@@TheDrivewayEngineer thanks for the response. I am gonna try will let you know. Hoping to finish next weekend will let you know. Just cutting down on hoses and fittings outside tank if it doesn't will mount filter outside tank.
Fuel regulators cost 100
OK!
Chicken nuggets cost 5.99
🤮🤮🤮
Thanks for watching!
