Will this fuel system work? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm installing an LQ4 into my '79 C10 with a Holley Terminator X. Are there any issues with this plan?

Tanks Inc baffled tank
Tanks Inc GPA in-tank pump
-6 line to Aeromotive 13129 bypass regulator
-6 return line from regulator back to the tank
-6 supply line from regulator to stock returnless fuel rails

Am I missing anything? It should work as long as the fuel rails see 58 PSI, right?

you should be good ,
i used all -6 on mine, no issues there
just make sure your pump can supply the pressure, i used a inline pump
not sure on the aeromotive,cant look it up here, but i used a vett filter reg on mine
been working for a lot of yrs now

Thanks. Here's the regulator: https://www.summitracing.com/parts/aei-13129

Also, should I be running a filter between the in-tank pump and the regulator, or between the regulator and the fuel rails, or both?

yeah, im at work and have limited internet access, so i get blocked from seeing it
im running a fliter between the tank and the pump,my pumps inline, then my reg has a built in filter
in your case i think between the reg and the fuel rails would be good enough

I just came across this diagram on the Aeromotive website. Seems to be what I'm trying to do.

On my LS swaps I use the C5 FFR. -6 SS lines. They used to be $50-$60. Now they are over $100 for a GM or Wix. That Aeromotive regulator is a bit more expensive but it should never need replacing.
I ran -6/C5 FFR on a LS2 sleeved and stroked to 427 cubes. RWHP 490. Never had fuel issues.
I've used Tank's Inc tanks on two LS swaps. I used Walbro 255 pumps supplied by Tanks.
Because I'm paranoid I do have a spare 255 pump that I've had for 10 years and never used.
Good luck with your swap.

Maybe look into a pwm deadhead system. Newer technology with oem parts. Lots of benefeits over a return type system. Overall cost will be about the same. https://www.vaporworx.com/
