I'm finally going single, this will be my first post here in this section of the forum.

I'm working on upgrading my fuel lines/system for my 94 FD.

Just purchased a bunch of fittings and an Aeromotive FPR, and after looking at several member's engine/fuel upgrades, I noticed that some members had their FRP mounted before entering the fuel rails. This would be opposite from the stock system and was wondering if it made a difference.

So far, I've decided to just running in series and mounting the frp after the fuel rail to the return line, should I be doing the opposite?

It should be running AFTER the fuel rails. I don't think what you're seeing is the FPR running before the fuel rails, rather the FPR on different sides. For example, you can have the fuel running to the rails from the front then the FPR on the back against the firewall. Or you can have the fuel running into the rails from the back, then have the FPR on the front. That doesn't matter, but you want your FPR to be the last thing in your fuel system in the engine bay.

Good point ...as I was planning on doing, but I've been following cohbra's setup and from the looks of his pics [page 4], it looks opposite from stock. FEED-FRP-fuel rail [parallel setup]-RETURN..... I may be wrong though.

On that particular setup, it looks like he has the fuel going into the rail from the back (firewall) then going through the rails and into the FPR then back to the tank. You see the fuel filter in the back, that's where the fuel is entering the fuel rails. You want a fine fuel filter before the fuel goes into the rails to avoid getting anything in your injectors.

In that pic, that's the same way I had my old setup. but I was running the lines parallel. I had my FPR mounted just outside of the fuel rail on the front of the engine (right behind the alternator).

Did you run ss braided lines on the feed hardline? I was wondering what the psi would be for the fuel from the fuel pump to the rails.

Some people on the board ran ss lines from the feed side, I was tryin to use Earl's compression fitting to AN fittings. Only caveat to that would be that the fitting takes up to 50psi.

Here is the link for the fitting:

I've used them, and bench pressure tested them. They seem to hold up fine if you're using the proper fitting on the proper size tube.
