I had one do that once. It worked fine moving it up and down. Mine had the tinest hole in the float. it would take on just enough gas when in the tank it would stay sunk. You might want to test the float.

Attach the ground strap with the clips that go on the sender nipple and the fuel line . The world doesn't need any more bald people

Personally I throw the factory ground strap away.I attach a wire with a small hose clamp then use a sheet metal screw to the body.Never have any problems with them after that.The sender wont ground thru itself.You need the strap or run a wire to the sender nipple.Rocky

Run a ground from the battery to the outlet.If that dosent work it almost has to be the float.Put the sender assembley in a bucket of water and see if the float arm moves.It dosent take much for them to hang up or be heavy.Rocky

If the sender is grounded then as said it has to be the sender assy itself (float/windings etc). I would fill the tank all the way up & if the gauge ain't pegged (Full) then it does not have a good ground because when the tank is full the rheostat windings are submerged & that is why the gauge is pegged with a full tank & it stays there for awhile before it starts to drop as the fuel level has to get below the windings so there's in effect no more dead short & it starts reading thru the actual resistance of the windings

i had about that same problem, it was a bad float. i knew the wiring was good, gauge was good, dash volt regulator was good, ground was good, tested the sender with an ohm meter... still the gauge never got above ~1/8. $11 for a new float on eBag fixed it. Now i watch the gauge go down down down from full very quickly
