Gaining access to the fuel filter on a 1999 Toyota Corolla is harder than replacing it. The easiest way to access the filter is through the driver's side wheel well. Taking off the wheel is involved. The filter can be replaced without removing the wheel, but removing the wheel means removing the smallest number of components to get to the filter. Replacement of the filter every 30,000 miles will ensure your fuel system is clean of debris and sediments.

Skill level:

Things you need

  • Line wrench
  • Jack
  • Jack stands
  • Tire tool
  • New fuel filter
  • New gaskets

  1. 1

    Ensure the car is parked on a flat, level surface. Chock the back wheel.

  2. 2

    Open the bonnet for access to the engine compartment. Disconnect the battery as a safety precaution.

  3. 3

    Raise the car up by the front cross-member. Lower the car onto jack stands. Remove the driver-side wheel for easier access.

  4. 4

    Locate the fuel filter inside the driver-side wheel well. It will be a canister-shaped filter.

  5. 5

    Slowly loosen the flare nut at the bottom of the filter with a line wrench to relieve pressure. Take off the banjo fittings and the gasket. Take the fuel lines off the filter.

  6. 6

    Pull the filter out of the bracket assembly. Replace with the new filter. Ensure the arrow is pointing toward the firewall. The arrow designates the direction of fuel flow.

  7. 7

    Replace the gaskets that were removed with new gaskets. Attach the fuel lines to the filter.

  8. 8

    Tighten the wheel back onto the wheel studs. Raise the car to remove the jack stands. Lower the car to the ground. Reconnect the battery.

  9. 9

    Start the car to ensure it runs smoothly. Observe the filter for any leaks.

Tips and warnings

  • Always replace the two gaskets when replacing the fuel filter.
  • Use caution when working around gasoline. Gasoline is highly toxic.
  • Use caution when raising the vehicle. Ensure the back wheel is chocked and the parking brake is set.
