4.2 - Fuel Gauge Sender ( )

Early X300 senders can develop a problem that results in the gauge not registering above three-quarters and/or being generally inaccurate. This is caused by contamination of the electrical track along which the wiper arm operates. Jaguar recommends a replacement unit, though some people have fixed existing unit by cleaning the track as follows.

To avoid spillage, the fuel level in the tank needs to be as low as possible and at least below an eighth full. The sender is located at the back of the tank and can be accessed by removing the trim panel at the back of the boot/trunk.

Remove the float pivot from it's plastic mountings. Clean the electrical track and contacts with a fibreglass pencil or similar gentle abrasive. Ensure the contacts are adequately tensioned before reassembly.

When refitting, ensure the arm movement is clear of the fuel pump wires inside the tank.
