fuel system

I am considering using an areomotive pump that I have that flows 150gph at 18 to 20 psi, to eliminate my carter. I figured I could get all the brass fittings at my local hardware store and the fuel lines at my local automotive store.

What size fuel lines should I run? I was thinking 3/8 id, or should I go 1/2 id.

Is 18 to 20 psi going to be to high for the vp44?

Do you need to change the return side? If so what size line?

Should I run 3/8 to the filter then 1/2 to the pump?

Do most of you guys relocate and use a new style of filter?

Sorry for all the questions but I already have the pump and I think I could do everything for about $50.00

3/8 is plenty, and 18-20 psi is the sweet spot!

Do you think the stock pick up will be able to handle 160 gallons per hour.?

The stock pick up handles 150 gph from a FASS with no problems.... so Yes.

18-20 psi is not too high. MY newer FASS spring runs 18-19 psi and I like it better than the previous 14-15 spring, but I can't give you solid data as to why. No downside I know of below 22 psi.

FASS uses 3/8" lines which is more than enough. The high flow systems out there use 1/2" but I believe that is just to provide greater fuel reservoir for the smaller Carter pumps and would not be needed with your Aeromotive 150.

Thanks. Do you have to drop the tank to change the lines?

Not if you have small enough hands

Look on FASS' web site for install instructions. They cover the subject well.
