Found the problem, the black 90 degree fitting right in middle of pic, is a90 coming out of the pump. I know these fittings are not rated for much but like almost everything the ratings on industry stuff is in the underrated side. They have been holding up in everything else I have used them in. I think the oring in the hose fitting side was compromised somehow. And I'm pretty sure they were oil tolerant. In pic below you can see the oil bubbling out.
