As long as the flanges are big enough, I don’t see why not. This is for a holding tank, not a fuel tank, so I don’t think there are any compatibility issues.

Just curious if you ended up using the nylon thru-hull fitting shown. If so, what did you use for a gasket? I am replacing all of the fittings and hoses on the blackwater tank on my Bene 331. I think they are identical to the ones on yours.
