I do have a problem with the fuel pressure regulator.
Symptoms are as follows:
*5psi MAX with first prime
*When Cranking I register 5 PSI
*When the return line is crimped prime is to 60psi
*With return line crimped Running fuel pressure and starting fuel pressure are right between 58-55 psi.
*Take off clamp on return line pressure quickly returns to 5 psi.
*FPR is not plumbed backwards – I originally thought that and checked it.
This FPR is brand new, should not be having problems with it like this. Has anyone else had issues or did I just get a dud?
