Lines Connected To Compressor

You need high-temperature line for the first few feet out of the compressor since the exiting air is really hot. We chose to have a high-temp line made at a local hydraulic shop with threaded O-ring A/C compressor fittings on one side and standard NPT fittings on the other. Although expensive, it’s good to 300 degrees and allowed us to use common NPT fittings for the rest of the system. For the inlet, we used a barbed fitting from an air conditioning shop and tapped into the crankcase breather hooked to the engine’s air cleaner. Maybe the blow-by from our tired 4.0L will help keep the compressor lubricated. The ports are labeled “S” (suction) and “D” (discharge) on the head for easy identification.
