The fuel filter on a 1989 Ford Taurus filters the gasoline coming from the car's fuel tank to get rid of the impurities in the gasoline so they don't make their way into the engine. You should change the filter every 30,000 miles. If your filter has more than 30,000 miles on it and you are having low idle issues (rough idle) or hesitation at low RPMs while accelerating, it could be the fuel filter. Either way, you'll need to replace the filter.
Tools Used: Catch pan, Pliers, Socket wrench, Socket set, New filter
Replace the Fuel Filter
Remove the fuse for the fuel pump. The Taurus's fuel pump fuse is on the fuse panel underneath the steering wheel. Use the diagram on the underside of the fuse panel cover to find the fuse. Use the fuse puller to pull the fuse out of the fuse panel.
Locate the fuel filter mounted to the firewall, next to the brake booster assembly on the driver's side of the engine bay.
Place a small catch pan underneath the fuel filter to catch any gasoline that will spill.
Remove the spring clip on the hoses running to the fuel filter. There are two of them, one for each hose. Pull the clips off with a pair of pliers.
Pull the hoses off the fuel filter, and allow the gasoline in the filter to drain into the catch pan.
Use the socket wrench to remove the screw bolt that holds the fuel filter strap in place. Then pull the strap down and remove the fuel filter.
Install the new fuel filter. You should install new spring clips (they should come with the new filter) on the fuel line hoses once they are reattached.
