Accurate fuel pressure is vital to your trucks power, efficiency and longevity. A truck experiencing hard starts, injector knocking or smoking may need a fuel pressure regulator (FPR). The fuel pressure regulator is located on the CP3/CP4 injection pump and can be serviced with the pump installed. DHD offers both house branded and OEM replacement options.
