From the parts diagram it looks like BX2200 fuel tanks are different than pretty much any later BX series like the BX2350, but I'm not sure if they're entirely not interchangeable. Has anyone put a newer BX tank in an older BX?
From the diagram it looks like some things moved like pickup, vent, etc., but as long as it fits physically and has the filler neck in the right spot it opens up more options for replacements.
