Washer - Diesel Sedimentor is a sealing washer used in the diesel fuel sedimentor (fuel filter/water separator) assembly on diesel-engined Land Rovers.

The washer provides a fuel-tight seal at a union, bowl, or drain point on the sedimentor unit, preventing fuel leaks from the filter assembly. It is used in conjunction with the sedimentor bowl or drain plug and should be replaced whenever the sedimentor is serviced or the filter element is changed to ensure a reliable seal.

Frequently asked questions

What is the diesel sedimentor washer used for?

The diesel sedimentor washer seals a union, bowl or drain point on the diesel sedimentor, the fuel filter and water separator fitted to diesel Land Rovers. It stops fuel weeping from the assembly. It fits applications including the Defender, Series II and IIA diesels, Discovery 1 and Range Rover Classic.

Can the sedimentor washer be reused?

Sealing washers like this are typically treated as single-use. Once seated against the sedimentor union or drain they lose their seal, so it's usual to fit a fresh washer whenever you service the sedimentor or change the diesel filter element. Reusing one often leads to a weeping fuel joint.

How do I confirm this washer fits my vehicle?

Fitment runs across diesel Series II and IIA, Defender, Discovery 1 and Range Rover Classic. Some are VIN-limited: Discovery 1 from FA393361 to WA799999, and Range Rover Classic up to HA610293. Use your VIN to confirm where a chassis range applies.
