fuel pump question??

[boogieman1]

I am building a new engine for my 72 c20 and have a fuel pump question. I have a crate 350 sbc and will be putting an edelbrock cam, intake and carb on it. I have read multiple places that with that setup you need to get the fuel pressure around 6psi. The problem is all the fuel pumps at that range I can find have 2 lines, but the original is a larger pump with 3 lines on it. Can I change this to a 2 line and if so what do I need to know? Any help would be appreciated.

Eddy carbs don't like more than 5 psi.
Easier to use any stock pump and use a fuel regulator to control pressure.

What intake are you gonna use?

Geezer is right about the carb being pressure sensitive. (he's pretty much right on everything he posts) With that said, if you want to run a two line pump you just cap off the return line. I've run edelbrocks without FP regulators with success before - personal preference, you can try the 2 line pump if it has too much pressure add a reg.

appreciate it, I just wasn't sure how hard it was to convert to a 2 line more than anything
