Appears to be also used in some KTM models. Seems pretty expensive there, too.
It looks like a plain ordinary cylindrical filter with hose barbs in and out, which are suitable for low pressure only (either on the suction side of an EFI pump or in a carb system with a low pressure pump). I'd be going to UAP/Napa knowing the hose sizes and how much room you have to work with, and find a generic one for probably 6 bucks ...
