When i cut the car off my fule press. goes from around 40psi to 0in about hour.(dont think this norm.) i have new fule line no leaks. i pinched the return line and it still droped so i gess it is a fule inj. leaking down...if so can this effect performance??(lean out or anything) it has no problems starting. runs ok..just the press. drops fast when cut off......if it is a injecter how do i find out witch one?
