The fuel filter is built into the fuel pump sender assembly
The 2003 Land Rover Discovery 2 does not have an external, standalone, serviceable fuel filter. Instead, the fuel filter is built into and is part of the fuel pump sender assembly, located inside the fuel tank. This means that the filter is integral to the fuel pump assembly and requires no maintenance.
The fuel pump has a coarse filter attached to the base of its housing, which prevents the ingress of large contaminants into the swirl pot. Additionally, a gauze filter prevents particles from entering the fuel pump itself. Surrounding the pump is a large fine paper filter element, which offers further protection to the fuel pressure regulator, engine, and injectors from particulate contamination.
This paper filter is not a serviceable item and cannot be replaced or maintained. It was designed to last the lifetime of the vehicle. Its presence removes the requirement for an external in-line filter.
To access the fuel pump and filter, the following steps must be taken:
- Remove the RH side trim casing.
- Pull back the loadspace carpet from the fuel pump access panel.
- Remove the six screws securing the access panel and take the panel off.
- Disconnect the multiplug and fuel hose from the fuel pump housing.
- Use LRT-19-009 to remove the locking ring from the fuel pump housing.
- Remove the fuel pump housing and the sealing ring, and clean the housing and mating face on the fuel tank.
- Fit a new seal to the mating face on the fuel tank.
- Fit the fuel pump housing to the fuel tank and use LRT19-009 to fit the locking ring.
- Connect the multiplug and fuel hose to the fuel pump housing.
- Fit the access panel and secure it with screws.
- Reposition the loadspace carpet.
- Fit the RH side trim casing.
