What You'll Learn
Locating the fuel filter
The fuel filter is typically located along the fuel line or near the fuel tank. The process for replacing a fuel filter differs between vehicle models, so it is important to consult your vehicle's owner's manual to locate the fuel filter and understand the specific requirements for your car.
To replace the fuel filter, you will need to relieve the fuel system pressure to avoid fuel spray. This can be done by removing the fuel pump fuse or relay and running the engine until it stalls. Make sure to turn off the ignition afterward and park your car on a flat surface with the parking brake engaged. If you need to, use a jack and jack stands to lift the car for easier access to the fuel filter.

Removing the old pump
Before removing the old pump, make sure you are wearing safety equipment and have a fire extinguisher nearby. Consult your vehicle’s owner’s manual to locate the fuel filter and understand the specific requirements for your car. Relieve fuel pressure by removing the fuel pump fuse or relay and running the engine until it stalls. Turn off the ignition and park your car on a flat surface, engaging the parking brake. You may need to use a jack and jack stands to lift the car for easier access to the fuel filter.
Now, to remove the old pump, first, cover the fuel tank opening to prevent dust and other foreign matter from falling into the fuel tank. Then, unplug the fuel pump and the lever sender connectors. Each connector has a standard snap-on latch, so just press the latch and pull out the connectors. Next, remove the screw that secures the seat cushion using a 12-mm socket wrench with an extension. Push the latch at the bottom side of each side of the seat cushion in the direction shown by the white arrows and lift the seat cushion.
Finally, transfer the wiring harness from the old pump to the new pump. Make sure that the wiring harness is properly laid out through the filter casing.

Inserting the new pump
Before starting, consult your vehicle’s owner’s manual to locate the fuel filter and understand the specific requirements for your car. Wear your safety equipment and have your fire extinguisher nearby when you do the job. Park your car on a flat surface and engage the parking brake. If needed, use a jack and jack stands to lift the car for easier access to the fuel filter.
Now, cover the fuel tank opening to prevent dust and other foreign matter from falling into the fuel tank. Unplug the fuel pump and the lever sender connectors. Each connector has a standard snap-on latch. Just press the latch and pull out the connectors. Remove the screw that secures the seat cushion, using a 12-mm socket wrench, with extension. Push the latch at the bottom side in each side of the seat cushion in the direction shown by the white arrows and at the same time lift the seat cushion.
Transfer the wiring harness from the old pump to the new pump. Insert the new pump into the new filter. Make sure that the wiring harness is properly laid out through the filter casing. Ensure that the O-ring can provide the needed sealing to avoid unnecessary rework later. A leak from this area could cause the fuel being pumped out by the fuel pump to escape back to the fuel tank, resulting in low or no pressure in the fuel system.
Finally, re-connect the hoses and the pump's electrical connector. To re-connect the fuel and vacuum hoses just insert the quick-connect fittings to their respective nipples.
