My fuel gage doesn't work at all, and I am thinking about checking it out before we leave for Branson. Does anyone know where the inspection panel is located to get to the sender on top of the fuel tank.

I called Marathon, and they told me it was "just to the right" of my filler tube (located in the 3rd bay on the passenger side). I cut my carpet in a couple places, but didn't find an inspection plate. Called Prevost, and they weren't sure where the inspection plate is located. The Prevost guy I talked to was not a technician, but he said he would try to help. Unfortunately, it didn't help.

I also asked if I could apply voltage to my dash gage to verify that it is working before I change the sensor. I didn't get an answer for that one either. Evidently the knowledgeable people were out of the shop on Friday afternoon. Does anyone know where I need to start with this problem?
