Fuel Pressure 80 PSI???
I just installed a Walbro 155 LPH fuel pump and my fuel pressure has risen to 80-85 PSI???
i noticed that the fuel pressure w/ the key on engine off goes to 20 PSI. Then i start it and it shoots up to 80-87 PSI. Then after a minute or two the car starts to drop rpm from 850 to 500 and shoots back up and its constant and at those point the fuel pressure drops to 20 Psi?? Also when i adjust the Reg there is no diffrence in the pressure it stays the same??
