How to Remove an Envoy's Fuel Filter

The Envoy is a luxury sports utility vehicle that was produced by GMC from 1998 to 2009. The GMC Envoy features an in-line fueling system, which means the fuel filter is connected to the fuel line. The fuel filter strains the fuel for impurities as it passes through the fuel line. Over time, the fuel filter can become clogged, which can lead to major problems with the engine. Fuel filters should be replaced according to manufacturer-recommended mileage.

  Park your Envoy in a safe location on even ground. For added security, engage the parking brake or apply tire stops to the wheels of the vehicle. Unscrew the gas filler cap from the driver's side of the vehicle. Open the hood and disconnect the negative cable from the battery.

  Crawl under the vehicle from the driver's side of the vehicle. Locate the fuel filter by looking below the driver's seating area near the fuel tank. The fuel filter is mounted on the frame rail near the driver's side of the fuel tank. You should be able to identify the fuel filter as a silver or black metal cylindrical container about 3 inches in diameter.

  Inspect the fuel filter and identify the attached black hose, which is the fuel line. Depending on your model, the fuel filter may also be partially enclosed in a protective shield. If your fuel filter has a shield around it, locate the bolts that secure the shield to the fuel filter. Remove these bolts using an adjustable wrench.

  Look at the area where the fuel filter meets the fuel line. You should see a few fittings over the area where the fuel filter meets the fuel line. Pry apart the quick-connect fittings. You may need to apply a flat-head screwdriver to the quick-connect fittings to pry them apart. Use a wrench to loosen and remove the filter feed bolt situated underneath the quick-connect fittings. This should allow you to disengage the fuel line from the fuel filter. Loosen the clamp bolt that attaches the fuel filter to the vehicle frame. Slide the fuel filter out of the mounting bracket and discard the filter.
