Sedimentor Seal for the diesel fuel sedimentor assembly.

The sedimentor separates water and sediment from the fuel ahead of the injection system. This seal maintains a fuel-tight joint between the sedimentor bowl and its housing, preventing fuel leakage and air ingress into the fuel circuit. For diesel applications.

Frequently asked questions

What is the sedimentor seal for?

The sedimentor seal keeps a fuel-tight joint between the diesel sedimentor bowl and its housing, stopping fuel weeps and air getting into the fuel circuit. The sedimentor itself separates water and debris from the diesel before it reaches the injection system.

Can the sedimentor seal be reused?

Sedimentor seals are typically single-use. Once the bowl has been disturbed the old seal can harden or take a set, so fitting a fresh seal is the reliable way to avoid fuel leaks and air being drawn in after reassembly.

Which Land Rovers use this sedimentor seal?

This seal fits diesel Series II/IIA/III, Defender (1987-2006), Discovery 1 and Range Rover Classic models with a fuel sedimentor or filter assembly. Confirm your vehicle actually has a sedimentor fitted, as fuel filter setups vary.

What are the signs the sedimentor seal has failed?

A failed sedimentor seal typically shows as diesel weeping from the bowl joint, or hard starting and rough running when air is drawn into the fuel. Renewing the seal restores a sealed fuel circuit and steady fuel delivery.
