Fuel Filter Air Bleed Valve WJN500110 for Td5

Fuel Filter Air Bleed Valve WJN500110 is used on the fuel filter head of Land Rover Td5 diesel engines to purge trapped air from the fuel system. Proper bleeding is essential for maintaining consistent fuel delivery, smooth engine operation, and reliable starting after filter changes or fuel system service.

A faulty or leaking bleed valve can allow air into the fuel system, leading to hard starting, rough running, or loss of performance. Replacing the valve helps restore correct fuel system sealing and ensures proper priming after maintenance.

Fits:

• Defender (1998–2006) – Td5

• Discovery Series II (1998–2004) – Td5
