Dancing Fuel Gauge

[sobamaflyer]

I replaced my tank early this year, after I did my gauge stayed on full all the time. I recently took the sender out and apart, cleaned it all up and put everything back together and it's working again but lots of the time if the car is moving I get ^this. It seems to be properly reading level as far as I can tell so far.

Any suggestions on what to tweak?

Thanks, Travis

Looks like an intermittent short or open circuit on the sender or one of the wires between it and the gauge. When you had the sender out, did you play with it's range and electrical resistance across the range, including wiggling it and seeing if you could get it to jump around like the guage does?

My oil level gauge did the same thing, then stuck full high level. I found a wear spot on the sender's range that had opened the circuit, resulting in the stuck-high reading.

I think the float contact sliders on the resistance wires do not consistently have good contact. You may have to take the sender ubit out again and rework those areas or buy a new contact senso. They are not that expensive, about $130.- for an SC. I rebuilt mine which was completetly stuck and now it works like new. There are few threads for rwbuilding fuel tank sending units here on Pelican.
