Need some help, Im stuck
Quick background:
Dual Walbros in tank, aeromotive boost reference regulator, 6AN feed and return.
Car ran last year fuel pressure at 58psi on idle. Swapped clutches changed nothing else and now I am only getting 25psi when i turn the key to prime it.
I am feeding directly to the FPR to rule out leaky injectors.
Replaced FPR - same issue
Nothing comes out of the return side of the FPR
Steady flow comes out on the feed line
I am stuck, and don't know what to check now. I have tried adjusting the FPR and get no change in pressure. Any suggestions??

Found the problem and want this to be a lesson you don't have to face. Pick the correct type of fuel line!!!!
This is what is left of the fuel lines that were in my tank. One of these is from the Walbro Kit! The other was from the auto store, and I made the mistake of believing that the line was good for in tank applications(thanks autozone).

Check with the vendors on the forum they supply the correct nylon in tank hose.
I just wounder who many other people on these forums complaining about low fuel pressure are having the same problem.
