I've had mine off to put a new seal in it. Found out the shaft was too worn so the new seal still leaked. I was going to take it out again and drive a Speedi-Sleeve on the shaft, but that keeps moving down the TODO list.

What do you want to know about it?

FYI as discussed in other threads the "seal" on those pump shafts is really a dust seal so putting in a new seal on a worn leaking pump will not stop the leak under pressure. They are basically "throw away" pumps when worn.
