Fuel pump with vapor purge valve assembly

A fuel pump comprising:

• a housing which is tubular and extends from a housing inlet end to a housing outlet end;
• an inlet plate closing said housing inlet end of said housing, said inlet plate having an inlet passage which provides fluid communication into said housing;
• an end cap which closes said housing outlet end of said housing, said end cap having an outlet passage which provides fluid communication out of said housing and also having a vapor purge passage which selectively provides fluid communication out of said housing;
• an electric motor within said housing between said inlet plate and said end cap, said electric motor having a shaft which rotates about an axis;
• a pumping element rotationally coupled to said shaft such that rotation of said pumping element by said shaft causes fluid to be pumped from said inlet passage to said outlet passage and to be pressurized within said housing;
• and
• a vapor purge valve assembly, said vapor purge valve assembly comprising:
• a vapor purge valve member located within said vapor purge passage, said vapor purge valve member being moveable between 1) a first position which blocks fluid communication through said vapor purge passage and 2) a second position which provides fluid communication through said vapor purge passage;
• and
• a vapor purge valve retainer fixed to said end cap, said vapor purge valve retainer having a first leg, a second leg which is opposed to said first leg, and a cross-beam which joins said first leg and said second leg, wherein said vapor purge valve member is stopped by said cross-beam at said second position
• wherein said end cap includes a first retention slot within which said first leg is located;
• wherein said end cap includes a second retention slot within which said second leg is located;
• and
• wherein said first retention slot and said second retention slot are separated by said vapor purge passage.
