Fuel gauge problem.

[nick crisp]

Mine started playing up yesterday, i've done 60 miles since top up and when sitting ticking over it's sitting at 3 quarters full which i expect but when I move off its moving up to full and back to 3 quarters again. Also when I turn ignition off the gaugue drops very slowly maybe 20 seconds, any ideas?

I'd guess that the up-and-down bit is just a result of how the float reacts/moves depending on the actual fuel level in the tank. So the changes under acceleration are just due to the fuel moving in the tank. Probably does similar under braking? It does seem a little odd that it'll do this, yet when you switch off it drops slowly. Just a design thing I think.
