The only USA made, flow on fail, direct replacement lift pump kit for 1994+ 6.5L Turbo Diesel vehicles with the DS4 injection pump.


  • Flow on Fail Design.  If the pump ever loses power or were to fail, fuel can still flow through the housing so you aren't stranded
  • Installs as easily as replacing a stock lift pump. Will bolt directly into place with no modifications necessary and plug into factory or upgraded wiring that uses a factory style plug
  • Internal inlet screen
    • The screen is not intended to be a pre-filter. We still recommend running a pre-filter if you deleted the fuel tank sock strainer
  • Internally regulated to <= 15 PSI
    • Pressure will drop slightly under load but will always maintain pressure to ensure the injection pump is never starved of fuel
    • See our other listings for higher flow pump upgrades if you need more flow or adjustable pressure
