Budget LS Square Body Fuel System 

An install video on this setup would be awesome, thanks for making our lives easy showing all the part numbers!! Definitely gonna go with this for my 5.3 swapped 81

Good video, I do basically the same thing except I use 3/8" brake hard line with short hose pieces at connections. It works well with an external pump also with a 100 micron pre filter, in that case I return to the filler neck so you don't have to pull the tank. I also place the Corvette filter/regulator as far forward as possible so a cool supply of fuel dead heads into the fuel rail. I use Walbro 255 pumps for everything and on vehicles that might suffer from heat soak or vapor lock sometimes I install a T into the fuel rail and tap the outlet and install a Allen plug with a .5mm hole (.017") in it to return a small amount of fuel keeping everything cool. Works like a dream.

"What are you all doing for your Ls swap fuel system?" Famous phrase Walker tuned knows what I'm talking about. Thanks for making this video.

“Saved to Favorites”. This is perfect, and perfect timing. Thanks!

Very simple and informative.... thanks for part numbers and all.... made my job easy....

Thanks that will work on my square and my Malibu except the sender. 🇨🇦🏁

Great video! Can you do a video of the installation of all the parts? I bet your subscribers will ten fold. Part 2 of the fuel system.

Love it man this is something different than I have seen done. You would need 3/8 for feed and 5/16 fitting for return line wherever needed but I like this idea for sure.

Nice video kept them coming, wish I was need you so I could get a tune

Good to see you Alex you need to do more videos 👍🏻

Thank you for this i was looking at $1600.00

👍 love to see more that OBS

Thank you man. Very helpful 👍

Awesome video! Same setup I used on my 2wd k5 build. Part numbers are different but same general parts!

Great job buddy 👍🇺🇸

Cool. Thanks for the info.

Walker performance is there any way you could post all the part numbers for the fittings and stuff I tried to stop the video to right them down thanks

Wish I would have seen this a few weeks ago before I butchered an 85 sending unit l!!!! Edit. Not a baffled tank

Thank you for putting this together! I am getting my @** kicked trying to find this pump. Is there any part number other EP381 that could help me? What was the AZ part number? Tried to see the box but can't. Thanks for the help

Great video, thanks. Can you make any suggestions for the square body dual tank switch?

I just Ls swapped an 84 k10.. I believe they installed a walboro pump on the rail, and it is very noisy. I installed a new tank with new pick up and sending unit a couple years previous…. My question is would a pump inside the tank be a lot quieter?

Guess u didn't have time for details? Why can't folks do videos like this??? He hasn't filmed his yard/cat /tractor/mentioned his dentist? Just The Facts. Excellent Video!

Wish I would have seen this video a month ago. I purchased the Holly EFI fuel pump module. It’s going everything needed for the LS including an in tank return. Not sure what I do with the truck intake manifold and it’s return line. Suggestions? Can it be blocked off or do I need to change to a system that doesn’t have a fuel return like the SS trailblazer setup?

do you have a parts list to order everything

Can you help me more about fuel system sir

Is this sending unit for drivers side or passenger side tank? Or will it work on both? I have passenger side, great video Thanks!

I have two questions I’m doing the same setup other than the pump 1. On the sending unit I have a purple and gray wire which one goes to the gauge and the power wire. 2. What do you use for the vent on the sending unit and a part number. Thks

Is this like 1987 tank? I need a tank but for a long box and they are a bit longer making them 20 gallon.

Hey bud how do I get ahold of you I’m going to need to have a tune done soon and have a few questions

I know O'Reilly's has rubber gates efi/e85 in bulk buy by the foot or w ,25foot hose I think part numer is like 17092 don't quote me on this and then they have buck barbs to screw into steel and efi hose clamp buy the box or each price isn't bad normally kept for commercial customers but they don't care to sell to a walk in I spent 7years as a manger and I would bet my truck title I could of gotten all those parts cheaper and if you buy much for like a restore then go in and ask to apply for a cash account it saves a ton on the little stuff or there the bendable steel stuff most people use for brakes but since the fittings are brass kinda illegal but seen a ton of them used but work great for fuel and transmission just ask if you can look at their fittings also there's some rolls of copperhead line it's actually can be used for brakes and it's fairly cheap and no bender needed just my two cents...when I get to that point on my square body I'm gonna run all metal lines like factory then depending if I carb 5.3 I'll thread it into the carb and if I efi I'll run metal to fire wall with a compression barb to efi hose

Please, if the return fuel system is not allowing fuel to go flow back to the track, what could be responsible for that? It's a friend picnic with a 5sfe engine with 4cycl

Is there a single pump that would work in that hanger for a cammed ls3?

Would this work for my 1986 Sierra? I’m putting a stock 99 5.3 in it

Having a hard time finding the AC Delco EP381 got any tips?

Hm.. mine already had sending units

Will all those parts work for a k5 blazer tank conversion in a 1986 k10?

Which fitting do you use for the top of the regulator going to the fuel rail? And can we run the rubber hose for the whole system from regulator to fuel rail?

Why would you need the tank sending United and another one on side?

Can you give me the part # for the fuel line?

What would I use or part number for dual tanks and got 6.0 ls with cam would I use walboros fuel pumps with same unit your showing or different

Do you have to tune it after ,🤔

What local part store's did you get the fragola fittings?

What would need to be changed if the truck is an 87 with the original tbi? Would changing only the pump work with the factory fuel line? 87 has a return line from the factory.

what do you do for dual tanks?

You think this will work for a 70 c10
