I received a new power steering pump. My pop turn my old one in for me and they said that there was a part on the old pump that they were trying to take off. They were not able to take it off. I have the new pump now, but am unsure specifically what part I'm needing.

Thank you guys!

Many pumps come without the reservoir so they look like the first picture. Ones with the reservoir look like image 2. A common missing part is the pulley that has to be pulled off and pressed on.
There was also an electronic orifice valve that came on the Astros stock pump. For that there is a bypass pipe you can install.
