Waterman 252000MF Outlet Manifold
                        If you have an older Waterman pump, this manifold replaces the fitting on the outlet side and gives you two more AN 6 ports. AN 8 in and three AN 6 out.											 						 			
                    
Waterman 350812 Fuel Pump Adapter Fitting, -8 AN Port to -12 AN
                        Fittings  are an integral part of any  racing fuel system. Simplicity within a  fuel system is the idea behind  WRC's "Sure Seal" fittings. These  fittings are reverse flared  for maximum fuel flow and the hose end is  O-ringed for a "Sure Seal!" Eliminate the chance for leakage with the  use of these aluminum fittings.
