This pump kit is designed to be a stand-alone system and is not designed to be used in conjunction with stock lift pumps. If your truck has been retrofitted with the Chrysler in-tank lift pump you will have to lower the fuel tank & delete the pump from in the tank. XDP offers a simple retrofit kit complete with instructions & the pieces needed to do this, part number BD1050302.
If you are unsure if your truck has been retrofitted simply check that the factory lift pump is still in place on the engine next to the fuel filter housing; if it is not there then your truck has the in-tank pump.
