My 1990 Mariner 32 has Crusader 270 engines and I need a fuel pump. None of the usual parts stores had the right pump. I live near Basic Power Industries and those guys are crusader experts, but they were stumped as well. They initially suspected it was part number CRU-97842 which was on back order. When it came in I took my pump with and compared. It's still the wrong part. The CRU-97842 has inlet at 7:00 and outlet at 6:00. My pump has inlet at 6:00 and outlet at 7:00. To make matters worse, there are no numbers on the flange.

The parts store clerks all said if I just ordered a "close enough" pump I could clock the housing how I needed it, but it looks to me like that's not right because of the way the bolts hold it together. It looks like it only goes one way. The guys at BPI said it's absolutely not supposed to be "clocked" and doing so would void the warranty.

Both engines have the same fuel filter, steel lines, and pump setup so whatever the mystery pump is, it's on both engines and appears to be stock.

Can anybody ID this pump so that I can order a replacement? My search-fu is exhausted, I've driven all over several counties, and I really don't know what else to do besides bite the bullet and convert to an electric pump. Pictures attached include my existing pump right-side flange, left-side flange, inlet/outlet orientation and the CRU-97842 inlet/outlet orientation.
