fuel pressure too high

ive got a b18b with a 14b turbo and im only running 5psi right now until i get this prob figured out... i have a jdm itr fuel pump, b+m fpr and guage and am only running the fmu for now

the problem is my fuel pressure is at 90psi at idle and the fpr wont do a damn thing regardless of how i move it.

Local boy! Does your gauge move at all? What about when you turn off the fuel pump, the system should slowly lose pressure.

The case with me! I took the line off the rail and still read 40psi!

Re: fuel pressure too high (B18T_EGhatch)

I had this problem and it turned out that I crushed the return line when I put the gas tank back in..

Try to make sure your return line is clear..

We put Anthony's gauge on my rail to set the Aeromotive FPR when I installed it. My gauge still reads 40 though. I don't know what brand his was, but it was a liquid filled gauge. Do you know of any good liquid filled fuel pressure gauges?

Re: (itr206)

well im pretty sure the guage is still good b/c when i shut off the car it does slowly lose pressure, and if i turn the key on but engine off to prime the fuel pump it goes up to like 35psi approx.

my main suspect is a restricted return line, but do any of u think that it is a possibility that boost in the vacuum line could have pushed on my regulator or the fmu so that it is stuck closed?
