G, yes I misspoke. I meant "elbow" ( don't know why I said "tee" as I do know the difference, I guess it was late last night). Some of them do have a check valve in them though. I think you and I have discussed about this before. I've got one off and I'll post a pic if I can remember.
Hooty, It could also be possible to make the pump a direct mount to the pto with the lovejoy. You'd have to figure out a way to attach the other end of the lovejoy to the PTO flange, fab a mount, and get the alignment fairly close ( the lovejoy will give you some leadway but it will still have to be pretty close).
