Re: Fuel Tank sender units

Bumping this as I've just had the sender unit out of mine to fix a "sticky" gauge.
A quick test - unplug the wire from the sender on the tank, earth the wire and turn on the ignition. If the gauge read full the problem is the sender in the tank, if the gauger reads empty the problem isn't (broken wire leading to the tank ect)
Make sure you run the tank low then the sender can be removed easily, twist the lock-ring then the sender just pulls out of the tank.
I got a new sealing ring and lock ring (from Anglia spares ?) and everything went back together ok.
The sender unit has obviously been apart before as the case was held together by a few twists of welding wire !
The problem turned out to be a sticking float pivot, a few minutes to clean the shaft and now it works as it should.
