Could it be a fuse? I cannot find a fuse diagram for it.
There would be a fuse, but if your temperature gauge is working, then the fuse is not the problem. Probably a fuse labeled "meter" or "gauges" fuse.
In most cases a failed fuel gauge is either a bad gauge or a bad sending unit inside the gas tank, and in 80 or 90% of the cases it is a bad sending unit, not the gauge itself.
There is a way to test which it is, but you need to know which wire at the fuel tank connector is for the sending unit. What one does is just briefly ground this wire to the frame with the key in on. If that causes the needle on the gauge to move, then you know the sending unit has the problem, not the gauge.

I would check the fuse first, and if that isnt bad, there is a float in the gas tank that sends a message to the gauge to how much gas is in the tank

Sounds like you have a ground problem, i doubt its in the sending units as both gauges are acting strange work, seeing that electricity likes paths of least resistance one gauge could be grounding through another. Bad grounds wreak havoc on electrical systems.

this is dependent on tire size an any add ons up top and the weight in the coach. best to ck emty. take a 2x4 and lay across tallest object on roof and measure to ground.

this problem is caused by a defective gas gauge sending unit, it is located inside the gas tank, u must remove the gas tank to replace the part

Have you pulled the stereo out to see if it had an external fuse in the back of it?
Is this a stock stereo, or is it an aftermarket?
