Hey guys I'm having fuel pressure issues. New, isr fpr, aem 340lph fuel pump,300zx fuel filter, new 72ilb Jim Wolf top feed injectors.

Fuel pressure will be at 38 psi w vaccume but after 10 minites of driving it drops to 20psi. I checked voltage to the pump and I'm @ 13.4v no vac leaks, tested fuel pump, no fuel leaks anywhere
