Fuel Filter: Description and Operation

Fuel is filtered at three locations:
- in-line
- in-tank
- fuel injector inlet

Fuel Filter And Lines:

IN-LINE FILTER
The in-line fuel filter has the following characteristics:
- It provides filtration to protect the small metering orifices of the fuel injectors.
- It is located downstream of the electric fuel pump module and is mounted on the underbody.
- It is a one-piece construction which cannot be cleaned. If it becomes clogged, it must be replaced.

The flexible fuel vehicle fuel filter and base is fuel methanol- and fuel ethanol-compatible. Use of a gasoline fuel filter and base will result in failure of the fuel filter and base. The fuel filter and base is located at the RH rear frame rail adjacent to the RH front corner of the fuel tank.

NOTE: When replacing fuel filter and bases, use the fuel filter and base specified for the engine being serviced.






IN-TANK FILTER
A nylon filter element is mounted on the fuel pump module inside the fuel tank and is used to protect the fuel pump module from fuel tank contaminants. The fuel pump module is snapped into a plastic retainer upon installation.

FUEL INJECTOR SCREEN
A filter screen is located at the top of each injector and is not serviceable. If the injector screen becomes clogged, the complete injector assembly must be replaced.
