Air Compressor - Auto Load Leveling

1999 Montana EWB with load leveling and accessory air inflator.

Does anyone know what that 11/32 rubber hose running from the air compressor's electric motor does? The hose is similar to windshield washer pump hose.

It's connected to a fitting on the motor and runs to a fitting on the inside of the left frame rail.

It has a T connector and a second hose about 6 inches long that doesn't appear to go anywhere and may have had a fitting in it at one time. (Fell out?)

It looks like the hose might be a vent for the electric motor. The line is not high pressure, but there is a bit of air that comes out when the compressor is running.

Of course the rubber hose under the van is rotting away.

I'm just guessing here, but it's probably to let water out that forms due to compressing humid air.
