Bobcat T300 fuel gauge not working

[PhilB]

Need some help here guys.
T300 Bobcat fuel gauge reads full all the time. Haven't really checked anything yet but I've always assumed it was in the control panel. Just recently thought that it could possibly be in the sending unit. Makes work difficult when you don't know when you're going to run out of fuel in the middle of a project or right before you're finished. Anyone have any experience with this and suggestions as to where I might start troubleshooting?

I would change out the fuel sending unit. Not an easy job because of the location.

Mine had split and so it was either full or empty, no in-between.

On my A300 I was able to barely reach it through the left side, top, access panel. Even then, it was partially under the pump and someone else had tried and messed up the top so I could not get a socket on it. Had to use wide mouth vice grips to unscrew it.

If you lift your boom up and secure it with the lift arm support device, you can remove both side panels completely and reach with your arm in and unplug the unit. Socket for the fuel sending unit was, I think, a 42 mm

Before swapping it out, there should be two wires going to the unit. Unplug one and see if the gauge changes. Then short then together and see if it changes. One should show full and the other empty.
