Description

Check part compatibility by using our vehicle filter options below. If you find your car, this part is compatible.

Designed to restore reliable fuel delivery and accurate gauge readings, the In-Tank Fuel Pump & Sender Unit – Land Rover Discovery Mk2 2.5 TD5 (1999–2004) (OEM WFX101080) replaces the original combined pump and float-type sender assembly housed inside the fuel tank. This unit supplies pressurised fuel to the engine while continuously reporting fuel level to the dashboard gauge. Worn or failing pump/sender assemblies commonly cause hard starts, loss of power, inconsistent fuel levels or engine misfire, and replacing them ensures smooth running, improved responsiveness and correct fuel gauge operation on compatible Discovery Td5 models.

• Easy Replacement: Engineered for straightforward in-tank installation using original mounting and wiring points.

Frequently Asked Questions (FAQs)

Q1: What does an in-tank fuel pump sender unit do?
It pumps fuel from the tank to the engine at the correct pressure and sends fuel level data to the dashboard gauge via a float sensor, combining two essential functions in one module.

Q2: Which vehicles does this part fit?
This unit is compatible with Land Rover Discovery Series II (Mk2) 2.5 TD5 diesel models built between 1999 and 2004 that use OEM reference WFX101080 or equivalent.

Q3: What are signs of a failing pump or sender?
Common symptoms include hard starts, engine hesitation/stalling, loss of power, poor acceleration, unusual fuel gauge behaviour (e.g., stuck or erratic readings), or the vehicle running out of fuel prematurely.

Q4: Can I replace this myself?
Replacing an in-tank unit typically requires dropping or accessing the fuel tank, working with fuel lines and electrical connections — many owners opt for professional installation to ensure correct sealing and safety.

Q5: Does this include all installation components?
This assembly typically includes the pump, sender float and mounting flange — seals/gaskets/clamps may need to be sourced separately depending on the vehicle’s condition.
