Jumpy gauge

[woodwizzard]

When the fuel tank is full the needle shows full and is stable, when it starts to drop it waves around quite alot. Is this most likely a dodgey sender unit?

Probably just the fuel sloshing around, mine moves a lot under acceleration and braking.

might be worth checking the electical conections especially the big one under the tank , this one cause me a few worries speedo fuel lights
spray of electrical clean and sorted

just an idea

Thanks guys. Not sloshing, its like an electrical switch being flicked on and off. Have checked and cleaned connectors and they seem ok. I know what mpg its doing, so can go by the trip, its just annoying having the needle jumping about.
