Abstract
A method of making a pump housing that is net-molded and immediately assumes its final shape and design specification without requiring more than de minimis secondary machining processes. The method utilizes molds and cores configured such that none of the fluid ports of the housing produced using the molds and cores have any intersecting geometry. The net-molded pump housing may also include a cross-tube insert providing flow communication between a fluid inlet port and a pressure relief port.
