"Bouncing" fuel needle...

Hey guys,

Every blue moon my 89 bronc's fuel guage needle "bounces" up and down from empty to pinned full. The other night I had about 1/8th tank of gas and was going to the local Texaco. The whole time it was moving back and forth from 1/2 to pinned past the full mark and back. Even when I stopped at a stop light. But after fueling and after that up until now, it has been normal. Weird thing is that I have less fuel now then I did when it was bouncing!

Anybody know what this is? know a fix??

Thanks everyone...

It could be the fuel sending unit in the tank starting to go out. Mine pegs full until a 1/4 tank then it will bounce for a bit and settle down at 1/8. I will drop the tank this summer and replace the sending unit as well as the fp. I think they run about $150.

Mine sometimes bounces when I reach about 1/8 of a tank as well. So I just don't let it get so low. Problem solved.
