I have a few questions for the more knowledgable and experienced.

I am running a quad throttle body, megasquirt powered setup and am at the fuel supply stage;

Do I require a fuel filter on both sides of my pump?

What fuel pressure should I run at?

Have you any advice on the fuel return line? I was going to plumb it back into the filler neck, is this an acceptable format?

Its very hot and humid here, should I be worried about the fuel warming up too much as it cycles through the supply and return?

Cheers.

Chris
