Larry,

Delco gauges are "Air Core" design. They stop reading when there is no power. When there is power, the read more or less correctly, over full or less than empty depending on the failure.

If your generator (APU) was running right and quit, the two first things I would check is can you hear the fuel pump running (click, click, click) and if it has a solenoid fuel valve (not all do), can you hear it open. Other than that, have you replaced all the rubber fuel line to the APU in the last 15 years?
If the answer to that is other than yes, and the test above are positive, then that is where to start.

If given just a little love and Onan can be DC3 reliable. (You have to show it you care...)

Matt
