Does the party look different in my MH or am I just looking in the wrong place?

I have a '03 DSDP. In '09, my one gauge would periodically drop to zero, the buzzer would come on, and almost as fast the gauge would go back to normal. The two air sender units are located under the front hood on the firewall. The picture in the previous answer is very accurate and the air sender is the brass colored looking pot. Another view can be found in a service bulletin you can get from Spartan. Call them and ask them for a service bulletin that would show a picture of the air sender units.
I got it on a recall service bulletin from '05. RSB05-400-001. There has been a recall on the wiring harness but not the actual air sender.
When I switched the wiring on the two sender units, the other gauge now malfunctioned which showed that it was a bad sending unit. I had one sent from Spartan and it was a simple replacement fix. Make sure you air down the system before you remove the bad unit. If you need more info do not hesitate to ask.
Good luck!!
