Description This Pump Is Brand New, Not Remanufactured The heart of the PSC 1400 pump is a larger ring and rotor which displaces more fluid per revolution. This makes it the pump of choice for Rock Crawlers that operate at low engine RPMs and have extensive steering modifications. The PSC pump housing is designed for use with the PSC Remote Reservoir Kit, sold separately. When using these items together, the P/S return lines are connected to the reservoir, not the pump housing. If you are not installing the remote Reservoir Kit, you can transfer the PSC pump internals to your original housing. Alternatively, you can order the Replacement Housing (fits 1994 – 1996 and 1999 – 2006 non-Alpha only).
