Some of our pump models have been designed with a four bolt inlet fitting. This design leaves a very wide open inlet passage proven highly effective for race engines. On occasion there is a need to reduce or adapt this inlet to one of our WN Style fittings to accommodate a different type of lower hose connection. This fitting will get you there. It features the four bolt pattern to interface to the pump and a WN female feature for the fitting to screw into.
