Power Gear air Leveling

Fred,
If you decide to go with a Vi Air, this may help. https://beaveramb.org/forum/index.php/topic,10152.0.html
The Vi Air draws move amperage than the Thomas so be sure to add a relay that is triggered by the check valve and supplies battery 12V via a fuse.

Fred, be sure to let us know if and where you find the original pump or its remnants.

OK, finally located the compressor. It is on the driver side, even with the front wheel on the inside frame, next to the AC radiator. You cannot see it just by looking underneath the coach. You have to crawl under there and its very hard to see unless you’re practically just below it. Bottom line, the aux compressor works, but sounds very raunchy, and pressure switch is bad. I’m going to replace both. I have seen bunches of them online, but most are advertised for other purposes, like airbrush, air horns, power tools, etc. I believe I will go with VIAIR 444C Chrome Compressor, 200 PSI max. Just need to know what pressure switch I should get for it. I believe it’s somewhere in the range of 100 to 130 PSI?

Fred,
It's a 120PSI check Valve. Hookup I did is attached.
