How to Replace a Fuel Filter in a Geo Trackerby Editorial TeamUpdated November 07, 2017
How to Replace a Fuel Filter in a Geo Tracker. The Geo Tracker is best remembered as a "funky but flawed runabout." Introduced as one of Geo's affordable new line of "international" vehicles, the Tracker was heavily marketed through the 1990s and then discontinued in 1998. The removal and installation of the fuel filter in the Trackers with the carbureted gas engines is an intermediate level do-it-yourself project.
Remove the Fuel Filter
Disconnect the negative battery cable from the terminal. Relieve the pressure in the fuel system while taking necessary precautions. Remove the fuel tank filler cap to release any built-up pressure, then reinstall the cap.
Raise the vehicle. Check to make sure the supports are safe and secure. Take a drain pan and several clean shop rags to mop up any spilled fuel.
Crawl under the right side of the vehicle between the front and back wheels. Set the drain pan under the fuel filter to catch any fuel that drains from the lines.
Press the fuel line clamp tabs with a pair of pliers and detach the fuel lines from the fuel filter. Slide the clamp down both fuel lines away from the fuel filter while maintaining pressure on the clamp.
Note the position of the fuel filter inlet and outlet nipples before removing the fuel filter. Remove the lower clamp bolt and loosen the clamp adjusting bolt. Remove the filter from the mounting clamp. Lift the fuel filter out of the mounting clamp.
Install the Fuel Filter
Work under the vehicle. Slide the new filter into its mounting clamp. Tighten the adjusting bolt until it's snug.
Turn the filter in the clamp so that the inlet and outlet nipples are in the same position as before removal. Tighten the adjusting bolt. Put the lower clamp bolt in position. Tighten it securely.
Connect the outlet hose to the top filter nipple. Connect the inlet hose to the lower nipple. Push the fuel lines up over the nipples as far as possible.
Compress the fuel line clamp tabs and slide the clamp up each line until it is secure over the nipple.
Position the clamps at least 1/4 inch from the connected end of the fuel lines, making sure the clamps are set over the nipples.
Reconnect the negative battery cable. Start the engine and allow it to idle. Check for fuel leaks and make the necessary adjustments.
Turn the engine off. Lower the vehicle.
The pressure in the fuel lines is maintained after the engine has been turned off. Always relieve the pressure in the fuel system, even if the car has been sitting cold for several hours, to prevent accidents and injury. Do not take the fuel pressure regulator or the air valve from the throttle body. Both are calibrated at the factory and are not serviceable.
