Whenever the truck is moving the gasoline gauge needle swings wildly as if the gasoline is sloshing around in the tank and the sending unit is following the waves up and down.
Any ideas on what the problem might be?

How much is your needle moving?

wiper or coil could be corroded. I'd pull the sender and check
it out with a meter.

May need to find a watchmaker to do surgery but now waiting for my new gauge to show up. | | | | | Joined: Aug 2011 Posts: 12 'Bolter | | 'Bolter Joined: Aug 2011 Posts: 12 | Many thanks to all who responded -- especially Denny!
