Chill guy, No one was putting B.U. down. Even if they don't sell the part, that's their business.
Actually I did call B.U. to ask about the part, but they didn't return the call yet, I'm assuming their pretty busy this time of year.
The book reffers to it as an "oil sending unit" in the world of auto's that usually describes a pressure sending unit.
Also, because B.U. didn't have it online, and I did assume they didn't sell it, so I called.
But just to let YOU know, the Club Car Maintainance service suppliment I got from B.U. states on page13-32
" NOTE Engine removal is required for repair of parts that are inside the crankcase.
Get busy livin, or get busy dyin.
