Mine went recently.
I decided to replace it with a tube type sender, which is more reliable and more stable in its readings.
The resistance is different though, so I replaced the guage at the same time.
Got them both from Demon Tweeks, and it cost about £80 for both (VDO stuff).
If you want to do the same you'll need to measure the depth of the tank where the sender goes in, and you want the sender tube to be about 30mm shorter.
