This is the video the world needs! I think I see this question asked just about everyday through out the surplus of ls swap groups I scroll through
Surprised more people haven't answered it. 👍
Awesome video, answered a lot of my questions about this swap, I have a ‘71 Chevelle and I think I will use the external set up for now, until I can afford a better in tank pump setup. Subscribed
Awesome video. Literally answered all my questions. Doing my first LS swap and I wish I would’ve found this sooner.
Awesome video , I watched many videos but none were as detailed as this one was .
Real nice & good info for both ways!👍👍👍
Great video keep up the very helpful info.Thank you.
Glad it was helpful!
This video helped me out so much!
Great video!
This was very helpful, thanks and sub'd!
Thanks for the sub!
Wow. I was thinking maybe I was going into overkill with an10 feed line to fuel rail on n/a 5.3. I’ve got other things to insert and swap out but ya. Your 1st setup is a mirror to soon to be mine too. Except that corvette fuel regulator and filter and walbro. Mine is a Holley pump 100gph 75psi and eBay fuel regulator. But ya. Glad I found your video. My anxiety is at rest. Lol. Be safe man
Good info thanks
No problem 👍
Well done
Great video. My LS swapped Camaro Holley terminator. Is the corvette filter is there a special year corvette filter ?
So glad I ran across this vid! I'll be doing this in a bit.. Sooo, if I use the Corvette filter/regulator can I keep my single (99' LS3 4.8 intake (no return)? I'm planning on running the Terminator-x system.. Thanks for explaining it all!!
Yes, you can keep the returnless rails since the corvette filter/regulator has its own short return line.
I went with braided ptfe lines but I swear I wish I came across these hoses and fittings first... good stuff tho 👌🏽
I considered the PTFE stuff, but the price on this other line was better.
I bought most of the parts through your links. I did not see the walbro external inlet and outlet fittings
Thank you...,👍🏿
Subbed!
Appreciate it! We've got a follow up to this video coming out today...our working fuel system on a running car
Excellent video!!!!
I just subscribed to your channel I have a few projects I'm working on the way you break everything down is very helpful
So i have a 1973 Chevy chevelle ls motor out an 07 Denali I believe it a 6.0 4l80e
.( I believe that I can have the out put shaft changed to 2wheel drive)
I plan on using the older clam shell mounts to save funds on my build
Do you remove the vats or tube the ecm?
Thanks for the sub! Sounds like that will be a great combo. I don't know much about changing the output shaft on the 4l80e...I've always picked up 2wd versions from the junkyard.
We used hp tuners to remove vats and do a startup tune for the car. I've read about a procedure where you do key on for 30 minutes or something to remove vats, but I've never tried it.
@@BLVCKFLAGD
I had a running donor so I unplugged the body control module an let it run to remove the vats I can't wait to see if it works
I'm can't w
What kind of line do you run from the corvette regulator to the fuel rail?
Did the caprice tank use a return?
So the caprice tank/pump will work on my Tahoe entake.?
What radiator is cheapest for a 67 chevelle ls swap?
Thanks
Can you use this same system for a 2004 crown victoria police interceptor with the 70 mustang/cougar 22 gallon gas tank ?
How did you put that wabro 450 fuel pump on the ss sending unit ... trying to use a caprice wagon on my elcamino
Haven't had good luck with external pumps. Seems after driving an hour it starts dropping pressure and pump sound like it's staving. Running 8an lines
Hey great vedios I am running a 02 4.8 with a return can u send me some part # to block off the 5/16 line can't seem to find anything here in canada thanks
If I don’t have a return on my tank will the corvette filter work as a return from the carb to filter
The hellcat fuel pump is rated at 525lph, and is good for up to 850hp. 1 is all you need.
Good info. Appreciate it.
Completely dependent on wiring and fuel used.
I did an 93 obs ls swap, drivetrain from 05 tahoe, returnless,, system,,, I did eliminate the obs fuel filter,, Gt fuel regulator/filter instead,,, Is it correct???
Nice
I have a stock fuel sending unit on my 84 firebird. I picked up 2 inline pumps that I want to run for my fuel system. For the HP I want (will be running at 6 to 700hp but want it ready for 1000) I need to run a 5/8 line. Should I have 2 separate lines to both pumps and then T into 1, or can I have it split as it comes out of the tank (meaning 1 feed at stock size into -10 fitting into 2 pumps and then to the front)
My only concern with running 1 feed from tank and splitting before 2 pumps, is that one tank may suck harder then the other and eventually lead to failure.
I don't have first hand experience with a setup like yours, but I picked up the stuff for one that I haven't finished. I would think separate pickups would be better for each pump. I was gonna run dual in tank pumps into -10 line for a turbo setup. At 6-700 HP though, the right single pump would work just fine I would think.
Have you ever had issues with the push fitting on the corvette filter/regulator? I had an issue with one I tried in which if not pulled all the way forward after being pushed in, it would pour fuel out. I ended up going with a "goodies" brand corvette filter/regulator which had the AN fitting hard mounted to the housing of the filter/regulator
My current filter looks like it might have that issue, but its only mocked up (you can see at the end of the video where it moves a little). There are a few plastic clips in the box which probably are necessary...I'll have to mess with it and get back to you. I haven't fired this one up or tested it yet.
@@BLVCKFLAGD I was under the impression the plastic pieces were for the inlet and return side, I could be wrong though, interested to see your results with it
I just put my regulator together this morning and noticed the white clips in the bag. Crap...
In reference to the gen3 fuel rails with the return blocked off, is there no worry about air build up in the rail? what method is used to push air out?
First time we fired it up, we just bled off the air out of the test port on the fuel rail. It's never been an issue at least on the Camaro setup.
The link for filter regulator goes to a filter that will not regulate at 58 its more like 72 FYI.
This dude's pretty cool.

Ok keeping iwth the BUDGET Theme, I have a RETURN style system on my 5.3 LS going into an 84 cutlass.
What would you recomend ;
1. a new compatible pickup with fuel pump in my stock tank? if there is one?
OR that Caprice tank with new pump spliced in?
whichever version you recomend, can you mention exact part numbers for pickup and fuel pump...
Can i repurpose the stock cutlass fuel feed line as my new return line by just making sure it goes into a return on pickup?
Most budget way I could think of...There are g-bodies that came from the factory fuel injected. If you can find a used tank from a fuel injected g-body, that would be the best starting point, as it should be baffled correctly and have the right pickup on it. Sometimes this is hard to find though because most junkyards poke a hole in the tank to drain it and don't sell them.
Drop in the fuel pump from almost any GM v-8 that was fuel injected, but didn't have TBI (those are much lower pressure) OR pick up a Walbro 255 (there's a bunch that would work, but GSS341 is a good option). It's only a few more buck for a 450 though, which will support more HP in the future.
Yes, use the stock fuel line as your return as long as its in good shape, then run a new send line rated for fuel injection.
@@BLVCKFLAGD thanks I eliminated return hoses, fittings , adapters and saved 75 bucks unless something goes wrong.
FYI; I already tried searching entire provincial gvt salvage and theres no tanks listed. our canadian population is 1/10 the density as usa, so we probly have 1/10 the amt of total cars to pick parts off and i will probly have to drive 6-8 hrs to neighboring provincial cities with more people in one city then we have in our entire province , lol. obviously that 6 hr drive/ 200 dollars in gas negates any money savings
I have a TBSS intake return less with a 97 obs return style fuel system. Can I just cap the return and hook the fuel line to the TBSS directly to the TBSS fuel rail without issue?
That's what I did here. I just capped the return on my intake and ran a single fuel line from the corvette filter regulator. The return will come out of that regulator back at the tank.
That -# is in 1/6" increments. So -4 is 4/16" or 1/4". -6 is 6/16" or 3/8". Bit of a mostly across the board standard. Just a bit of minutiae for ya.
Love little facts like that. Thanks for the info!
Isnt that pushock fittings I think that's what the line and fitting are. It was gonna be what I used on my s10
yes...the aeroquip hose I like uses push-lok fittings. Way better than building the other other AN style IMO
So on a return less system while utilizing the corvette regulator do you have to return it from the regulator to the tank or can you just cap it off ? I think I kinda answered my own question while typing this , so is the return on theregulator how the regulator regulates ?
The corvette filter/regulator at the tank has a short return line, so only 1 fuel line runs up to the rails.
But is the short return required or can it be caped off
If I use that Walbro 450 for my in tank pump, will it have to much pressure for the corvette fuel filter/regulator? should I go with a smaller pump? Thanks for the vid!
I think it depends on the brand of filter. Some cheaper ones say more than 255lph and fuel pressure goes up.
Yes.....a True hotwired 450 will over run the regulator slightly. Easy to tune around, but yes it does.
@@tunerdadtunerdad7927 Thanks !
Great break down
I have a 1974 2dr caprice
Would that 95 caprice tank fit into my 1974?
And with it being fuel injection ready would I still need the Corvette regulator an filter?
Can I get that areoq line from that company it self an what Did that 20feet of line cost you?
I would think the caprice tank may fit with a little modification since the filler is in the same spot, but I'm not 100% sure. For my chevelle I know I'll have to cut a small portion of the floor, but it's a rust bucket so not an issue for me. On a nice car, you may not want to do that.
For the corvette regulator, it would depend on the type of fuel rail on your swap engine. If your fuel rails have a regulator built in (return style) you don't need anything else and the factory stuff in the caprice tank would work fine.
If the fuel rails are returnless, that's where you would use the corvette filter/regulator. You could still use all the caprice tank stuff, just run the return from the corvette regulator to the return on the tank and run your single line up to the engine.
I got my aeroquip line from summit. I think it was around $95 for 20 feet of it. I do have links to everything I used here blvckflagd.com/youtube/2-ls-swap-fuel-systems-you-can-build-on-the-cheap/
@@BLVCKFLAGD
Ok
So I'm going to do fuel setup first so do I still need Corvette regulator and filter?
And thank you for the response
@@louisziegler3690 if you're running a returnless system from the fuel rail on the engine, yes. If you are running a return line the full length of the car, no.
I did explain a little further in this video if you haven't watched it yet ruclips.net/video/KJlfyED8ZZ4/видео.html
@@BLVCKFLAGD thanks going to do fuel system this week
Do you have a video showing what you did to modify the 94-96 Caprice tank into the Chevelle? I'm doing an LS swap on a budget into a 68 Cutlass and stole your idea on the fuel tank assembly issue. I haven't gotten to that point yet. I'm just curious what I have in store.
We don't have a video yet, but will when we finish the work. When researching, others had to cut a little out of the trunk floor near the center and extend the tank straps a few inches.
@@BLVCKFLAGD
I'm still trying to figure out what motor and transmission mounts to use. I'm using a 5.3 from a 2wd 2005 Yukon and the 4L60e. Do you have any suggestions, short of fabricating my own? I see tons of options for Chevelles and other A-Body cars. Nothing specific says Cutlass. But I think 3rd gen A-Body cars are the same in this aspect, right?
Also, I wonder if I can get by with just extending the straps? I have a good trunk pan and don't really want to cut it up. I've got a lot to do before I get that far. Hopefully I can see what you do first.
@@joshuanewcomb1929 I would think any of the a-body mounts would work for the engine. For trans mount, it's pretty easy to slide it forward or back and drill new holes where it mounts to the frame. Don't know on how much space you need on the tank. We won't get to doing ours on the chevelle until late winter or early spring.
My question here.
Corvette FuelFilter/Pressure regulator.
With return style at intake manifold.
The two lines from the tank goes to the two ends on the filter/regulator.
The return line from the intake then goes where??
Since you have the short return line from the filter/regulator, you can cap off the return line at the intake. It's not needed anymore.
On my 1970 chevelle can I use the stock tank with external pumps or will I still need an i tank pump with the external pump?
Yes you can I have a 68 cutlass stock tank eternal pumps drive it cross country many times
This may be a very obvious question so I apologize, but when doing an external set up, would I remove the pump out of my in tank hanger assembly? I’m having a difficult time understanding how to make this work using a stock fuel tank
You don't need both. If the vehicle you're swapping is already fuel injected, you have nearly everything you already need in place. My opinion is the in-tank pump is superior to an external in most cases...it will run cooler, quieter, and last longer.
You may only need to swap out the stock pump for one that delivers more fuel depending on the vehicle.
What vehicle are you working with?
@@BLVCKFLAGD I’ve got a 1993 Mustang with the 2.3l engine currently. I’m going to be using a gen 3 lm7, just a cam, springs, and headers kinda like your set up. What I saw my dad do on his ls swap (93 OBS Chevy truck with a 6.0) was to use an old Monte Carlo fuel pump and put that into his in tank hanger assembly. That pump makes a bit over 60 psi though
I have a single supply fuel rail so I don’t need to worry about my return it’ll do it on its own?
You would use the corvette regulator/filter at the tank with a really short return, then run a single line up to the fuel rail. Same setup I'm using on the camaro with more details in this videoo ruclips.net/video/KJlfyED8ZZ4/видео.html
So what stock fuel rails do i run, the return less or the or the return style?
Either will work with whatever setup you go with (I just capped the return on my fuel rails since I'm running the corvette filter/regulator).
Where do you get power from… msd 6014 doesn’t come with wiring for efi tank
You can wire it up to key on hot source. Preferably use your key on 12v to trigger a relay going to the battery for the fuel pump.
Hi bro how u doing 2003 intake from a Tahoe with the returns line to do I still need to use the Corvette regulator it's just a daily driver stock car
If it has a return, it means the intake has a built in regulator. You don't need the corvette filter/regulator but you will have to run the return from the engine to the tank.
Main reason I ran the corvette filter/regulator was to simplify plumbing and run only 1 fuel line the length of the car. Corvette filter is near my tank, so the return is only about 1ft long.
@@BLVCKFLAGD okay thanks for the help bro this is my very first swap I got everything hooked up as a rough draft just got to go through and check everything and reroute the wires longer and I should be good to go it's got a couple more things I got to tighten up
What micron is that fuel filter? Do you have a link? Thanks!
Wait i just seen you have a link to everything 😳
Glad you found it!
Can you use e85 with the corvette fuel regulator?
I believe so. The rest of he fuel system has to work with it as well -- especially hoses.
installing a LS fuel cell no return line. do I need a regulator?
Yes. Run the corvette filter/regulator at the tank. It will have a short return line but you won't need to run a long line up to the engine.
Does the corvette regulator need powder?
Trent Anderson no, but it does have a wire for a ground. I believe mainly so you don’t get static building up in the fuel lines
How much hp can the corvette fuel filter regulator be good for?
I'm sure it would support 500hp NA easily. I wouldn't be comfortable using it above that or on a boosted setup.
I have used it to 720whp with a boost-a-pump and a 255 on a boosted setup.
so do you have an internal and external pump? or just 1 of them
We're running only an external on the camaro. Just a single.
@@BLVCKFLAGD Oh ok. Im trying to get my fuel system done on a ls1 swapped 240z im trying to figure out all the parts i need for it. If I do get an external pump will it work fine with a datsun fuel tank? I didnt know if i should just get an oem fuel tank or have a fuel cell fabricated.
@@thewinchester8996 That all depends on the tank...I don't know enough about 240z's, but if it came with fuel injection stock, you should be able to swap out the internal fuel pump in the tank for one that will flow enough for the ls swap (depends on what's in there).
Usually for an external pump setup you need a tank with a sump at the bottom (similar to a fuel cell). External pumps don't do too well if they have to suck fuel out of the tank.
They do make retrofit kits that will drop an internal fuel pump into a stock tank without too much effort.
POSSIBLE PROBLEM, with your fuel setup starting about 7 min into video. DID you actually set it up like stated in the video and did it run reliably?
Firstly why r u running a filter , then pump, then filter regulator combo? you could save money eliminating first filter.
Secondly , wouldnt sucking through the first filter exacerbate the possible problem that these inline external pumps have, theyre are meant to only push fuel under pressure and dont suck very powerfully or reliably? thats what driveway engineer channel said i think.
Yes, it's setup like in the video and runs reliably. I've got a follow up video you can watch about it.
I think it's a pretty accepted practice to run a pre-filter before an external pump (an internal would have the little sock filter on it). It was inexpensive and only filters out bigger stuff. Internally it's a cleanable metal mesh so it doesn't really restrict any flow either. Should make the pump last longer by keeping junk from getting in the pump.
The filter/regulator after the pump is for smaller particles and protects the injectors from getting clogged.
The car has a fuel cell, and the external pump is below the cell, so gravity always keeps fuel in it and it's never sucking anything to get fuel.
I'm also surprised by how quiet the setup is. People always talk about how loud externals are, but this doesn't seem any louder than a stock gm internal.
On the returnless what size is that?
For the line, we used -6 for the whole car
For the fittings, I believe one is 3/8, one is 5/16
There's a blog post with links to a lot of the things used here: blvckflagd.com/youtube/2-ls-swap-fuel-systems-you-can-build-on-the-cheap/
@@BLVCKFLAGD thank you so much . There were a few things that were keeping me from getting this done. I'm about to order now.
THIS CANT BE RIGHT can it ? VERY EXPENSIVE! Im Doin a 5.3 LS/vortec into a gbody. In canada using amazon to source parts im up to $375 cdn/$300 usd for fuel system and i might still be short a male 6an fitting or 2 for fuel pump !
thats , walboro pump$113 cdn, evil energy filter $42 cdn, 4 adapters for pickup and return style fuel rails$64 cdn, 16 ft 3/8 fuel feed line hose kit with fittings $63 cdn, 16 ft 3/8 return line$43cdn
my whole cutout motor only cost 445 cdn. Do you know of cheaper place to source these fuel line parts?
i could maybe save the 43 for return hose and try to use former feed hose as the retrun line but then im possibly looking at a leak and fire hazard and my car is only insured for liabilty and would get a mere 300 for the car if it burnt!
Yeah, you can use your existing line as return hose and save some on the fuel line, but that sounds pretty close for cost. You might be able to find the pump or some of the fittings cheaper, but that's with some searching. Summit and amazon seemed to be the best deals.
I do have links here blvckflagd.com/youtube/2-ls-swap-fuel-systems-you-can-build-on-the-cheap/ if you want to compare costs for what I used, but I bought all that stuff a while ago too, so prices might be different now. I tried to find the cheapest stuff that would still get me by a tech inspector at the track, so that's what's in the list. If that's not important to you, you could save money in some areas.
don't use that Corvette regulator With Boost Use a boost reference regulator
Good info 👍
Thousands of corvettes are boosted and so is mine. The regulator is just fine for boost. Boost referencing in most cases is actually worse because a pumps flow is drastically limited as fuel pressure rises unless you have a HP pump or a vortech 50/70
@@boss.manlsswapking2219 ...Just informing. A 1 minute Google search provides a ton of information. If you cant do that, then you aren't smart enough to boost anything, so it's a moot point.
@@boss.manlsswapking2219 Lol....34,000. Yep, you dont know much. If you need any advice, just ask.
U Don’t understand what how much this helps with my swap🤦🏽♂️
corvette filter $50, expensive maintenance ? $10 filter sounds cheaper, good internal pump, n good regulator , return lines, fuel evap system on tank
Nope Corvette filter is built in regulator
