triple gear pump o rings

[Luckydog018]

ok So I have a 2000 Bobcat mini 325. And I have a leak on what bobcats parts website calls triple gear pump. So I took the tee fitting off and replaced the oring with a factory o ring. and still leaks. took it back apart cleaned it up and tried it again, still leaking. so one more time this time new o ring and some black sealant and still leaking. i feel NO burs or anything on the tee fitting or in the threads of the pump.

Has anyone else ran into to? how can i fix it? Thanks

Inspect the pump housing for very fine hair line crack at the threads.

I did not notice any blemish at all on the threads
the one thing that i did notice is the washer on the fitting is kind of beveled not sure if it should be flat or beveled??

So i took the pump to a shop and when they tried to mill it, it uncovered a crack in the housing down through the threads. so looks like im screwed and need to buy a pump. anyone have a good one out there? pump # 6674941
