    • 1). Park your car in a safe place, loosen up the fuel filler cap, open the hood and locate the power distribution box at the front left-hand side, or driver's side, of the engine compartment.

    • 2). Start the engine and let it idle as you remove the lid from the power distribution box and unplug the fuel pump relay. Marks on the inside back of the lid or the relay itself should identify the unit.

    • 3). Let the engine stall and then crank the engine for about three seconds to relieve the remaining pressure from the system.

    • 4). Raise the back of the vehicle using a floor jack and safely support it on two jack stands.

    • 5). Locate the fuel filter at the back of the car--between the fuel tank and rear bumper--and clean both fuel lines connected to the fuel filter to prevent fuel contamination once you disconnect the fuel lines.

    • 6). Remove the evaporative control system, or EVAP, canister next to the fuel filter if you need more access to the filter. You can remove the canister using a wrench or ratchet and socket.

    • 7). Disconnect the fuel supply line from the fuel filter--the line going to the engine--using a backup wrench and a flare or line wrench to avoid damage to the line.

    • 8). Grasp the quick-connect line fitting at the other end of the filter and press the lock tabs. Slightly twist the fitting from side to side to remove any dirt from the line connection. While pressing the tabs, push the fitting against the filter and then pull it away to disengage the line.

    • 9). Remove the filter from its mounting bracket and set the new filter in place, making sure the arrow on the side of the filter case points towards the fuel supply line.

      Connect the supply fuel line by hand to avoid damage to the threads and install the quick-connect line to the other end of the filter. Tighten the supply line to 20 foot-pounds, or 27 Nm, using the backup and flare wrenches.
