With the DF150-175-200s Zuke went the way of Yamaha and use a plastic housing with the replaceable metal cup and gasket.  Getting it all seated perfectly isn't as easy as it should be.  If you don't line up the tit perfectly the cup won't fully seat, the gasket won't seal, and you'll warp the plastic housing when you bolt it down.

 Sounds like the guys who changed the pump out last fall might have caused this . . . ?
