Buell/H-D part number P0080.3AB NEVER existed.
Mid-2004 thru 2009 all XB regulator housing sans regulator/upper O-ring seal CORRECT part # is P0080.3A8
Several still left in dealer system. Check with local H-D dealer and/or online. Original list was $68.90.
$249 is a tad high for a decent quality operational used pump considering the fact that I sell NIB ones for not that much more.
Good luck.
