Fuel Filter: Description and Operation

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

In-Line
The in-line fuel filter and base has the following characteristics:
- It provides filtration to protect the small metering orifices of the injector nozzles.
- It is located downstream of the 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.

In-Tank
A nylon filter element is mounted on the fuel pump inlet inside the fuel tank and is used to protect the fuel pump module from fuel tank contaminants. The fuel pump inlet filter is not serviceable. The fuel pump module must be replaced.

Fuel Injector Screen
An injector filter is located at the top of each fuel injector and is not serviceable. If the injector screen becomes clogged, the complete fuel injector must be replaced.
