This pump was part of a power steering upgrade kit the PO put on the truck. I've identified the other bits, like the steering gear, but not sure about this pump.

Obviously it is a Saginaw pump, I can tell it is newer because it has a GM O-ring fitting on the output vs. the older inverted flare, but other than that, I have no idea about the application. I was hoping someone would recognized the return line and can shape and could name an application.




AND unrelated, but look at this gem I saw at the boneyard while pulling parts for the hydroboost.

I'm digging the "slotted rotor" in the second pic, I just gave one of those canned hams away at the swap meet...IIRC, I pulled it from a Chevy 1500 mid to late 80's

Hope that helps
