Did Barth (or Spartan) put chassis air connections to add supplemental air for use by a tow truck? Sometimes when buses are towed, the engine is running to keep air in the system.

Troubleshooting some leaks in my system and figured i'd ask before plumbing in a valve and connection to connect to my shop air to pump up the system.

The coach in question is an 89 Regency w/ Spartan chassis.

Yes my regency has airline connections on 3 separate tanks. Mine are in the front, so I carry a 50 ft airline hose. I expect Steve VW to chime in here. His Monarch has one airline connection that I saw at the last meet.

On my Aristocrat and Monarch there is/was a valve and quick connect nipple in the front near the vacuum generator. I switched them to female quick connect to make it easier to fill my tires. I carry a double ended female in case a tow truck couldn’t tap the other. I left the valve in place.

That male nipple and valve should be very obvious.
