Fuel Sending Unit Or Fuel Gauge??

2001 FLHT ELECTRA GLIDE.
My fuel guage needle pegs back and forth with vibration. I took the tank hold down bolts out as if to remove the tank, and it seemed to stop jumping around. Does this sound like the sending unit or the gauge???
Help Please....

Sounds like a bad connection under the gauge to me.

A bouncy fuel gauge for that year bike is common, sounds more like the gauge.

The gauge is only a means of registering the output from the potentiometer in the fuel tank. A bouncing gauge will be the result of fuel sloshing in the tank more so than the gauge itself.

Re: Fuel Sending Unit Or Fuel Gauge??

This is my first time on this site so I'm not sure how to post, but I have a problem in this area. The fuel gauge on my 98 road king classic is not working properly. It reads full all the time and the light comes on at 1/2 full. I changed the sending unit and float assembly today but still doing the same. Any ideas?

Looks like you posted OK

If you use the info in this post, you can test the output of the sending unit and determine where the problem is. Quite possible the float may be hanging up on something inside the tank.
