this truck has a lot of miles but the guy really likes the truck. the fuel presure will not go over 18 psi .I changed the fuel pump 3 time and still will not got over 18 psi. Do you have any other thing i can check for this problem..i was told that the oil pressure switch ,switches the pump up to increase the pressure .is this true? please e-mail me back with any other ideals .thank you

You're leaking fuel pressure could be the injectors, fuel pressure regulator and fuel pump check valve
