How to Change a Gas Filter on a 1989 Chevrolet Scottsdale

The Scottsdale is the midlevel trim edition of the 1989 Chevrolet full-size pickup. The gas filter on the truck is an important component in the fueling system, which helps power the vehicle. The fuel filter scrubs the gas in the fuel line of impurities before it flows into the truck's engine. Over time, the fuel filter will blog up with dirt and other contaminants. Changing your fuel filter regularly can help keep your truck in good working condition.

Tools Used: Adjustable wrench or quick-release tool, Gloves, Protective eye wear

Change a Gas Filter

Park your truck in a safe area on level ground. Apply the parking brake to prevent the truck from rolling while you are changing your fuel filter. Open the hood of the pickup and disconnect the negative battery terminal. Go to the driver's side of your truck and loosen the fuel filler cap to relieve the vapor pressure in the fuel tank.

Crawl under the truck from the driver's side. Look below the driver's seating area. Locate the fuel filter on the driver's side of the transmission. You should be able to identify the fuel filter as a black, oblong cylinder about 3 inches in diameter attached to the fuel line.

Use an adjustable wrench to remove the bolts that connect the fuel filter to the frame rail. Set the bolts aside. Use the adjustable wrench or a fuel filter disconnect tool to remove the fuel line from both sides of the fuel filter. This will free the fuel filter from the fuel system to allow you to remove it. Set the old fuel filter aside.

Use an adjustable wrench to connect a new fuel filter to the fuel lines. Make sure that the arrow on the fuel filter is pointing forwards towards the engine of the truck. Use a wrench and the bolts you previously set aside to attach the fuel filter to the frame rail of your truck.

Crawl from underneath the truck and go to the driver's side. Tighten the fuel filler cap back onto the fuel tank. Connect the negative battery terminal to the battery.
