This is the master rebuild kit for all Big Dog Motorcycles fuel injected models from 2007-11. The kit includes all necessary O-rings, seals, clamps, new fuel pressure regulator and new fuel filter to overhaul your existing fuel pump assembly. Note; this kit is only for rebuilding the fuel pump assembly only and not the pump itself. The pump is not a serviceable unit and must be replaced as a whole. If you need to replace the fuel pump unit, see our other listing for a rebuild kit that also includes the new fuel pump.
