The gas tank on a Jaguar not only contains fuel for the engine, but often holds dirt and grime in there as well. Those materials can do harm to the fuel-injection system, so it's best if they stay out of the process entirely. To stop them from entering the system, a fuel filter is installed between the tank and the fuel rail. This filter should be changed regularly to avoid fuel problems. In this case, the project vehicle is a 2005 Jaguar XJR, but the process is similar for other Jaguars as well.

Set the jack underneath the chassis of the Jaguar and lift it up in the air. Put the car on jack stands so that you can access the underside of the vehicle. Open the gas door and remove the gas cap, releasing pressure in the fuel system.
Crawl underneath the Jaguar and locate the fuel filter, which is hidden behind a bracket, connected to the gas tank via the fuel lines and mounted to the chassis. Unbolt the fuel filter bracket from the vehicle using the 3/8-inch ratchet and socket.
Disconnect the fuel lines from the fuel filter using a line wrench. Remove it from the car. Install the replacement fuel filter so that the arrow on the side of the filter is pointing away from the gas tank and towards the engine. Install the fuel lines using a line wrench and reinstall the bracket using the 3/8-inch ratchet and socket.
Lower the Jaguar off the jack stands and onto the ground. Start the car and check to see if there are any leaks. If you find any, tighten up the connections on the filter with a wrench.
