I'm putting the finishing touches to my swap and need to identify the ports on the 2000 Silverado power steering pump I'm using. There are three ports. Can anyone tell me what the three ports are used for? I have two hose bib type ports and one large threaded port near the bottom of the pump.
The Threaded one is the output port.. the other two are return port to the reservior. This pump most like was from a Hydro Boosted truck. If you are not using the Hydro brake system, use the lower port for the return and cap off the upper one.
