Why is my gas gauge pessimistic?

[Eric Perplies]

The fuel level sensor (in mine and probably in your coach) Looks like
toilet float. It's a roundish brass sphere at the end of a long rod.
On my coach the rod is about 3 feet long. The control end of the
fuel gauge contains the electrical contact that remain outside your
tank. If the length of the float arm is too short it could cause the
symptoms that you have mentioned.

The two possibilities that comes to my mind are that the float at the
end of the arm has somehow slid on the shaft making the shaft arm
shorter than it should be. A second thought is that a fuel level
sensor for another (shallower) fuel tank has been installed on your
coach. My tank is a large rectangular box with the fuel level gauge
mounted to street side near the top close to the center of the tank.

Good luck,
