Next project - Pro Flo 4

[Dleslie212]

Well my rear end rebuild finished up a few months ago, and I’ve been itching to do SOMETHING else to my truck. So my next project will be installaing an Edelbrock Pro Flo 4 system and was wanting advice or pointers from anybody that’s already done this. This is going on my 1977 K10

I want to keep my dual tanks and use a new electric pump to pull through the newly replaced six port switching valve, but I’m also considering using Edelbrocks fuel sump kit. My ideal installation would be two new in-tank electric pumps, with a way to use the switching valve to switch which pump is running, but I don’t even know if that’s possible.

Check out https://forums.edelbrock.com There's a section for the PF 4 there. Lots of info. I have one on my truck and there are a couple of others that have them here as well. I don't have a square body, so I won't get into my setup, but the other two I was referring to are sq. body owners and hopefully they will chime in. I will say there have been a few issues with Edelbrock's sump. I'd look at other avenues for your fuel supply.

Completely possible! I just did this exact thing on my truck. I used stock, 1978 non-baffled tanks, 2x Holley fuel pump modules, and a Harnessworx LS harness with a new Pollak valve that can handle EFI pressures. You can check out my install here:
