Re: Air Compressor Help!!
since yoru compressor exploded, the air system may not hold air. It might all leak out of the busted compressor. If so, you can find all the plumbing pieces you need to cap off the main air supply running from the compressor at any local hardware. The air fittings are almost certainly standard pipe thread.
If the compressor is damaged in such a manner that the system does still hold air, that's even easier. The easiest place to "tap in" to the air system with an external air supply is under the bus at the stock air tanks. They should already have drain valves built into the tanks. These valves are almost always standard 1/4 inch npt fittings, once again available at any hardware. Plug your 12 or 110 volt air compressor hose into this air tank and it'll supply air to the air brake system.
like others mentioned, this method is dangerous and should only be used to move the bus to a safe location until you can install a new engine driven compressor. Compressors many times have full pressure lubrication, plus engine coolant connections, and some even get the air from inside the engine air filter housing.
