Fuel filter head return valve (VUB503950)

This is a fuel filter head non-return valve from the Allmakes 4x4 brand.

It prevents diesel from flowing back through the fuel filter head so the fuel system stays primed, and is usually replaced when it leaks, sticks or the engine is hard to start after standing.

Compatible with Land Rover Defender and Discovery 2 TD5.
