Not to tell your stuff but I hope you remembered to get the water pump[or a new one] too, and also a fan blade cause they both turn backwards from the "normal" rotation of the time that our trucks were made. Although they will fit and function to some degree, the older fan and water pump on the new stuff [turning backwards] will over heat in certain slower speed situations like driving in traffic or slower speeds. That is a lesson I learned the hard way in 1990 and have not forgotten. Jim
So that nut at the back of the pump is for what? Extend the hose rearward? Ha. I threaded the old pump flow valve in there but I think I might have left the but from newer pump in there.

How do I contact Lee? I may go that route.


Someone pointed that out about the pump earlier. I think mechanicalman. I grabbed the whole thing and ended up getting a new pump because I didn't like the looks of the one from the junk yard. While I was there I grabbed a Taurus fan so I'm skipping the mechanical fan... I also kept the motor in the rear l6 position so I would have shroud issues.
