Abstract
A fuel pump includes a housing which is tubular; an inlet plate closes one end of the housing and an end cap closes the other end of the housing. The end cap includes an outlet passage and a vapor purge passage. An electric motor within the housing rotates a pumping element to pump fuel through the fuel pump. A valve assembly of the fuel pump includes a valve member located within the purge passage, the valve member being moveable between a first position which blocks fluid communication therethrough and a second position which provides fluid communication therethrough. A valve retainer fixed to the end cap includes a first leg, a second leg which is opposed to the first leg, and a cross-beam which joins the first leg and the second leg. The valve member is stopped by the cross-beam at the second position.
