Product Details
Diesel fuel systems rely heavily on consistent low-pressure delivery from the tank to feed the engine-mounted high-pressure injection pump. When the in-tank lift pump begins to fail or the fuel filter clogs, it starves the system, leading to drivability issues and potential damage to expensive high-pressure components. This kit bundles everything needed to overhaul the delivery system properly in one shot.
Kit Includes
In-Tank Fuel Pump / Delivery Unit: Replaces factory part # 2114705894. This is the primary low-pressure feed pump that sits inside the fuel tank, restoring proper volume and pressure to the front of the vehicle.
Diesel Fuel Filter: Replaces factory part # 6460920701. It is critical to replace the fuel filter anytime a new pump is installed to ensure unrestricted flow and prevent old trapped contaminants from damaging the new unit.
Fuel Pump Tank Seals (x2): Replaces factory part # 2114710579. These elastomeric O-rings seal the sending unit and pump assemblies to the top of the gas tank. Reusing old, swollen seals guarantees a diesel leak under your rear seat.
Fuel Line Hose Clamps (x4): Replace factory part # 07129952104. Fresh clamps ensure a tight, secure, and leak-free connection on the feed and return lines during reassembly.
