fuel pressure regulator (aero)

I'm about to get an aeromotive FPR for my build. Ill be running a spoolboy canister w/ a walbro pump. Can someone explain how the line connects from the stock line to the fpr and from the fpr to the stock rail? I couldn't find a writeup or anything on it.

Yup. Have to.

it should go from the feed line from the tank, to the rail, to the fpr, and then to the return line back to the tank

I'm saying how do you litterally connect it? Is there a special fitting or do I have to just use clamps?

Making the connections depends on how well you want the reliability and your wallet. You could go as fancy as braided line, and AN type fittings for the best method, but it can add up fast. IDK how well regular hose and worm clamps would hold up over time.

What AN fitting would fit our rail?

AN-4? IIRC, that's what folks use, but they also might adapt that to the ones with the pressure test port. I have no actual experince doing this, so take it for what it's worth.

Edit: Well on neons anyways. I used JIC fittings and copper tube on my Raider for the fuel system.

Only due to the fuel pump outlet tube rusting off, and Mopar/Mistu wanting over $600 for a new FP module.

the stock rail has a clip on fitting. How would that work?

If your using a stock rail how are you even going to install the regulator? Or are you coming off the pressure port? If so you need a NPT to AN adapter for whatever size line your using.

Thats the clip on for the fuel rail, youll need to take the valve out of the port on the other side and get an adapter piece. I would recommend running -6 an lines

I planned on running the regulator before the rail, as does the AGP return line kit.

ok I was assuming after the rail. Anyways AGP sells the fittings you need to connect everything individually.
