Relieving the Fuel System Pressure

• 1). Make sure the engine on your Tracker is cold. This will prevent possible damage to the catalytic converter or causing a fire.
  
  
• 2). Set your transmission to "Neutral" (manual transmission) or "Park" (automatic transmission) and apply the parking brake.
  
  
• 3). Unplug the fuel-pump relay located on the driver's side under the dashboard.
  
  
• 4). Loosen the fuel-tank filler cap to release fuel vapors in the tank and re-tighten the filler cap.
  
  
• 5). Start the engine and let it run until it stalls from lack of fuel. Crank the engine again two times for about three seconds each time to make sure you have relieved the fuel pressure in the system. Then turn off the ignition.
  
  

Removing the Fuel Filter

• 1). Chock the front wheels.
  
  
• 2). Disconnect the negative battery cable using the wrench.
  
  
• 3). Raise the rear passenger's side tire and wheel assembly using a floor jack and support your Geo on a jack stand.
  
  
• 4). Put on your goggles, get under the vehicle just in front of the rear tire and wheel assembly and locate the fuel filter in front of the fuel tank, mounted on the cross-member.
  
  
• 5). Place a small drain pan under the filter.
  
  
• 6). Look for a small pressure-relief screw on one end of the fuel filter. If your filter is equipped with this screw, use a small socket and ratchet to remove it. This will relieve the residual pressure in the fuel line. Allow the fuel to drain and drip on the drain pan.
  
  
• 7). Hold the hex nut molded on one end of the fuel filter using an open wrench and loosen the bolt holding the fuel line to that end of the filter with a flare wrench.
  
  
• 8). Loosen the fuel line from the other end of the fuel filter using the open-end and flare wrenches.
  
  
• 9). Remove the fuel line bolts the rest of the way with your hand and keep the bolts separate. They are of different size and need to be replaced in their correct place on the new filter.

  Make a note of the position of the U-shaped notches on each end of the filter, where the fuel lines seat, so that you install the new filter with these notches pointing in the same direction.

  Wrap a shop rag around one of the fuel-line fittings and detach the fuel line from the filter by hand. Use the rag to absorb any fuel remaining in the line.

  Detach the other fuel line from the filter.

  Loosen the mounting-clamp bolt from the fuel filter using a wrench, just enough to slide the filter off the clamp. Remove the filter and make a note of the "inlet" and "outlet" marks on the filter so that you install the new filter with these marks pointing in the same direction.
  
  

Installing the New Fuel Filter

• 1). Slide the new fuel filter in the same position as the old one and install the clamp bolt finger-tight.
  
  
• 2). Insert one of the new copper gaskets that came with your new filter on one of the fuel line bolts so that it seats under the bolt's head. Then insert the bolt in the line fitting and install the other new copper gasket on the bolt so that it rests against the line fitting. Thread the line bolt by hand on its corresponding end of the fuel filter.
  
  
• 3). Install the other fuel line on the filter using the other two new copper gaskets and make sure both fuel lines seat properly on the U-shaped notches.
  
  
• 4). Tighten the mounting-clamp bolt using the wrench.
  
  
• 5). Tighten the fuel-line bolts using the open-end and flare wrenches.
  
  
• 6). Make sure the small pressure-relief screw on one end of the fuel filter is tightened, if your filter uses this screw.
  
  
• 7). Lower your Geo Tracker using the floor jack.
  
  
• 8). Plug in the fuel-pump relay located on the driver's side under the dashboard.
  
  
• 9). Connect the negative battery cable using the wrench.

  Cycle the ignition key between the "On" and "Off" positions for three times and leave the key about three seconds in each position to prime the fuel system.

  Check for fuel leaks at the filter.
