Just a thought, can you take some small pieces of paper towel or oil absorbent pad and place them around the pump to help try and track down the leak. I had a similar and this trick helped me find the weepy fitting.
As long as you are sure it is not a hose fitting leaking you are going to have to pull the pump and get it rebuilt.
Sorry buddy but no other way around it.
rebuilding it should not be that bad. A good hydro shop should turn it around in a few days.
That's what I was figuring on. It shocks me because there is not much time on it at all. Shouldn't these things last thousands of hours before a rebuild is necessary?
By the way is this Bill from LBI?
