SOURCE: how to fix jaguar x type fuel gaug when the tank is full is not working but when it haft tank is work why? you know how much to fix it do i have to remove the fuel tank to fix it

the fuel gauge on a jaguar x type is regulated by a floating gas gauge that measures resistence; the float drags a contact across a board that has variable resistence. You can retrieve the sending uint from the gas tank by removing the carpet cover and the spare tire assembly from the trunk. Then you carefully tap the retaining ring from the tank and remove the fuel sending uint. You will see the float, the assembly and the resistor board. carefully take the unit apart, and the sliding joint where the float meets the board (which is made of copper) needs to be cleaned, I suggest Brasso, a metal shiner. Rub it well into the copper joints and let it dry to a haze, then buff it to a brilliant shine. Reassemble the sending unit and replace it into the tank. The unit will work perfectly from empty to full for about another 20 years, and the two dollar investment in the Brasso is well worth is; saves you about 60 bucks on a new sender

sounds like you got the float stuck when you installed the new part, have seen this hapeen often

Testimonial: "this was helpful, part of my own suspicions and if this is from a jaguar mechanic, I would say very helpful if there is no relay involved.??"
