I am getting ready to attack the fuel tank on the GT-R. The NPT fittings for fuel going to the low pressure pump and the fuel return are on top of the tank. Other than an NPT male fitting of the correct size, what goes inside the tank to draw fuel into the outgoing line? Does anyone know the thread specs for the NPT fittings? I think I want to get to AN 8 ASAP off the tank connections. Is that correct?
