The fuel filter must be replaced at least every five years or 50,000 miles (80,000km). The is a maximum replacement period. Good preventive maintenance dictates that the fuel filter be replaced once a year, or every 10,000 miles (16,000km). However, since the amount of dirt and water in the fuel varies greatly, the filter should be replaced whenever you suspect it to be clogged. Typically, the symptoms of a clogged filter are a lack of engine performance under full throttle conditions, especially at high rpm, even though the engine operates normally under moderate driving conditions. With severe clogging, the filter may cause poor running under virtually every operating condition but idle. One way to check out the filter is to follow the steps below for removal and then drain the contents out of the filter through the inlet. Drain the filter into a tin can rather than a glass or styrofoam container. While it is normal for a light concentration of particles or a few drops of water to be trapped in the fuel on the inlet side of the filter, large amounts of water and heavy concentrations of dirt indicate dirty fuel and, probably, a clogged filter. If you find a great deal of dirt trapped in the filter, it is a good idea not only to replace the filter, but to have the fuel tank drained or pumped out as well.
An electric fuel pump is used on these models and the filter is in the engine compartment. A connector, for checking the fuel function, is located under the battery tray. With the engine running, disconnect the connector. When the engine stops, no pressure will remain in the system.
REMOVAL & INSTALLATION
First, you MUST reduce the pressure in the system as follows:
- Open the trunk and pry up the lid located in the floor which covers the electric fuel pump.
- Start the engine and allow it to idle.
- Disconnect the fuel pump connector. Allow the engine to continue idling until it stalls. Then, turn off the ignition key.
- Disconnect the negative battery connector.
- Remove the air cleaner assembly as required.
- Using an open-end wrench to hold the fuel filter stationary, loosen the bolt for the banjo type connector on top of the fuel filter with a box wrench. Do exactly the same with the inlet connector on the bottom of the filter.
- Remove the bolt or nuts attaching the filter to the bracket and remove it.
- To install the new filter, reverse the above procedure. It's best to torque the bolts for the fuel line banjo fittings. If the banjo fitting washers are damaged, replace them. The outlet fitting is torqued to 18-25 ft. lbs. in all cases. The inlet fitting is torqued, to 25 ft. lbs.
- Reconnect the fuel pump, start the engine and check for leaks.
