Land Rover Part Number: WQM500020 - Fuel Pump Drive Module
WQM500020 is a Fuel Pump Drive Module fitted to the vehicle fuel system on petrol applications. The module controls the electrical drive signal to the in-tank fuel pump and provides the primary interface between the vehicle wiring harness, the pump motor and the level-sender within the combined pump/sender assembly; it manages pump activation for key-on and engine-run conditions and regulates power delivery under varying load states. When replacing this module, ensure the part number and engine application match the original to maintain compatibility with the in-tank pump and sender design.
