Recently my fuel gauge began to fluctuate a lot. You could watch it bounce up or down a quarter tank.

It has stabilized now but appears to be reading a half tank off. It fills to the full mark but at the half tank level, it takes a little over 20 gallons to fill it up.

How do I troubleshoot this.

You might want to check the grounds, but you will be probably need to replace the sending unit.
