Most coaches that I have seen are provided with quick disconnect hose fittings from the converter, and are usually only in the steer compartment, but occasionally are in the rear also.

If your converter has not provided one the best place to add one is in the steer compartment. If you have an auxiliary air tank in your steer compartment tap into that tank air line. If you have no tank easily accessed look for the fitting that Prevost tags as the converter air supply. That attach point is auxiliary air and has air system protection. If there is no tag identifying that connection point find a large auxiliary air supply line for any of the house air circuits. That is a good point to tap into for a quick connect fitting.

The thing to remember is you want to protect the integrity of the aux air supply and to make sure you tap into it downstream for any protection valves. In that way you can have a catastrophic failure of that aux circuit and you still maintain your braking systems.

If we know your converter we can get more specific as to suggestions on adding a quick connect.

I have only one, in the steer compartment on a manifold with other house circuits and I am easily able to reach all necessary points on my 45 foot coach with a 50 foot hose. I would be reluctant to add one in the rear because the heat and road grit will eventually affect the function of the quick connect.

Doubt you could produce enough volume to properly run a 3/4 inch Impact for very long.

The day has not yet arrived when I have to run an impact wrench of any size from my coach aux air.
