I just added on board to my brother's '89 Sidekick. I used an inline oiler and a small air filter before the compressor. After the A/C compressor there is a air/oil filter, pressure switch, safety valve, pressure gauge (in the dash), and a small coleman propane tank as my air tank. I run it up too 100 psi. I can fill a 30x9.5 15 from 16 psi to 22 psi in less than 10 seconds when the engine is idleing. Oh, one more thing. The compressed air runs through the condensor that the stock A/C used.
