Abstract
A fuel pump includes an O-ring seal to provide sealing contact with a diaphragm seal between a valve housing and associated valve cover interface despite some loss of clamping load between such mating parts. Also, a molded O-ring type ladder seal is used to maintain seal integrity between the valve housing and associated pump housing interface despite some loss of clamping load therebetween. Machined O-ring grooves are desirably provided in opposite sides of the valve housing to accommodate the O-ring against the diaphragm seal and the molded O-ring type ladder seal against the pump housing.
