How to Remove Fuel Filter From a 2000 Jimmyby Dan Ferrell
After months of service, rust, water and other particles trapped in the fuel-filter element gradually diminish flow from a vehicle's fuel tank to the engine, affecting performance. If left unchanged, the filter eventually will starve the engine of fuel, causing a significant loose of power. Before that happens, you can replace the filter on a GMC Jimmy and help restore the engine's power.
Relieve Fuel Pressure
Disconnect the ground (black) battery cable using a wrench.
Loosen the fuel-filler cap to relieve the pressure inside the fuel tank.
Locate the Schrader valve at the end of the fuel rail, where the fuel injectors connect. This resembles the air valve on the tires of a GMC Jimmy.
Connect a fuel-pressure gauge equipped with a bleed valve and hose to the valve, and insert the hose into a proper container.
Open the bleed valve on the pressure gauge, and let the fuel in the line drain into the container.
Close the gauge valve, and disconnect the gauge from the Schrader valve.
Removing the Fuel Filter
Raise the rear, passenger-side wheel/tire assembly off the ground, using a floor jack, and place a jack stand under the frame for support.
Put on safety goggles, then locate the fuel filter on the frame rail, near the fuel tank and passenger side of the vehicle.
Remove the hairpin clip from the outlet fuel line connected to the filter (the line going to the engine). Slightly squeeze both clip legs with your fingers as you push the legs into the line fitting. Then, grab the clip back tab, and work it out of the line fitting.
Wrap a shop rag around the line fitting, and carefully separate the line from the filter. Soak up the fuel dripping from the filter and line with the rag.
Disconnect the feed-fuel line from the filter. Hold the filter in place using an open-end wrench as you unscrew the line-retaining nut with the flare wrench.
Loosen the filter mounting clamp, using a standard screwdriver.
Remove the filter from the mounting clamp and the vehicle.
Installing the New Fuel Filter
Place the new fuel filter in the mounting clamp, with the arrow on the filter case pointing to the outlet line and away from the fuel tank.
Tighten the filter's mounting clamp with the screwdriver.
Connect the feed-fuel line to the filter. Start the line retaining nut by hand to prevent damage to the threads. Then, tighten the retaining nut with the flare wrench as you hold the filter in place with the open-end wrench.
Install the hairpin clip that came with your new filter into the fitting of the outlet fuel line. Make sure the clip legs lock on the outside of the line fitting.
Push the outlet-line fitting against the fuel-filter nipple until you hear the clip snap in place on the nipple. Slightly pull on the line fitting to make sure it is locked in place.
Lower the vehicle.
Tighten the fuel-filler cap.
Connect the ground (black) battery cable, using the wrench.
Turn the ignition key to the "on" position to pressurize the fuel system. Start the Jimmy's engine, and apply the parking brake.
Check for leaks at the new fuel filter.
