How to Install a Fuel Filter on a 1989 Buick Electra Park Avenue

The fuel filter in a 1989 Buick Electra Park Avenue removes dirt from the fuel before it can reach the engine. As the dirt builds up in the filter, the engine begins to starve for gas. If this happens, you will notice your Electra having less and less horsepower, until it eventually quits working. To avoid this problem, install a new fuel filter every 15,000 to 20,000 miles.

Remove the gas cap to relieve pressure on the fuel system.

Locate the silver fuel filter underneath the Electra's passenger side frame rail. The filter is located in the middle of the passenger door and has a gas line connected to each end of it.

Using an open-ended wrench, loosen the jam nut that secures the fuel line to each end of the filter. Pull each gas line away from the filter. Have a pan ready to catch any gas that leaks out of the gas lines.

Use an open-ended wrench to remove the bolt that secures the filter to the frame rail.

Place the new filter against the frame rail and secure it to the Electra with the bolt and wrench.

Press the gas lines onto each end of the filter and tighten the jam nuts with your fingers. Tighten each jam nut with a wrench.

Close the gas cap.
