Where and how can i test fuel pressure before the schreader valve? I am trying to track down a fuel pressure problem and want to see if it is the fuel pump, fuel filter or FPR.

 

Replace the fuel filter and then check it at the schreader valve.
Fuel must get to the FPR to set the pressures that you need to check.
Without the FPR the fuel pressure can be 95-100psi.

If you would have said how do I check fuel volume then that would be a different story.

Here is that story, some good ideas:
