Petrol tank sender unit float...

[David Stepney]

When I had my tank sender unit out, I found that someone previously had shoved a cork into the skeletal remains of the float. The float finally collapsed into dust as I tried to get the cork out, so I just pushed the cork onto the angled wire where the float had been. Crude but effective. The gauge now works, but does not sink below the 1/4 mark, so when it gets anywhere near there, I add fuel.

But Ruairidh, you will probably want to do the job properly.
