1990 3297 - Crusader 270 Fuel Pumps

[Gag_Halfront]

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.

What am I missing? It looks like the first pic (old pump?) has them in the same orientation as the last pic (newpump?)?

This site shows the CRU-97842 in stock. Perhaps you can contact them to see what theirs look like.

Not the best pic because of the angle I had to hold the pump for the light to clearly show the IN and OUT markings. If you look at the alignment of the inlet/outlet in relation to the pump arm and not in relation to the orientation of the photo, it's a little easier to see. I've marked up the pictures to help.

Could you just move your lines and not the pump housing ?

Can you rebuild it using parts from the new into the old?

I can get some tubing and bend some new lines, but in my experience that's more of an art than a science. Getting the right pump would be ideal. This could be a plan B.

I've considered this as well. This could also be a plan B.


I just like to reduce risk as much as possible when it comes to a fuel system. Bending lines and doing heart surgery on a pump are both possible options. if I can get a proper replacement for the OEM pump, that feels like a little less risk. Thanks for the suggestions. If I can't source the right pump, one of these will probably be the answer. Not sure which one.

The lines may have enough slack, perhaps ( a fitting ?), so you don't have to make new. See the thing is, now the supplier for those pumps is likely offshore and not the same one as back in 1990, therefore you may have to fit something to make it work unless you can find some NOS parts. Even so I would be leery of 30 year old rubber diaphragms in a fuel pump. Matching fittings can present a problem as well....inverted flare angles need to match.

Just a guess on my part, good luck.
