Frequently asked questions

What is the M12 union nut for?

This M12 union nut clamps a fuel pipe to its mating union or component port in the fuel delivery system. It draws the pipe's flare against the seat to form a fuel-tight connection on the Land Rover Defender, Discovery 1 and Range Rover Classic.

Which Land Rovers does this fuel union nut fit?

This fuel pipe union nut fits the Land Rover Defender, Discovery 1 and Range Rover Classic with the M12 fitting. On the Defender it covers cars up to VIN WA159806. Confirm your fuel pipe uses the M12 union before ordering, since fuel unions come in several thread sizes.

What should I watch when fitting the union nut?

The M12 union nut fits easily, but the pipe flare and seat must be clean and undamaged to seal. After connecting fuel pipework, check carefully for leaks before running the engine. A cross-threaded or over-tightened nut can distort the flare and weep fuel.
