"The shop manual for my 8.2s MPI engines says that the fuel system should retain pressure for about 30 seconds after the fuel pump shuts down. Mine go to 0 immediately after the pump shuts down. I followed the troubleshooting guide to determine if the leak is at the pump, the injectors or the pressure regulator and determined it was at the regulator. Replaced the regulator as the manual said it was defective, and even with the new regulator it still goes to 0 right after the pump shuts down. The gentleman at Crusader says do not worry about it but the Crusader shop manual says I have something wrong... any ideas?"
