Claim:
A method of manufacturing a primary fuel system shut-off valve assembly for an automobile, said method comprising steps of: forming a housing having a substantially cylindrical wall with a more open end and a more closed end defining a limited diameter nozzle inlet opening to the housing; forming a radially outwardly extending outer ring in the housing, wherein internally of the housing, the ring defines a channel; providing a valve door assembly for the inlet, including a movable flapper door and a seal between the flapper door and the more closed end adjacent the inlet; inserting the valve door assembly into the housing through the more open end of the housing; affixing the valve door assembly within the housing, such that a member of the valve door assembly is configured and arranged to be received in the channel of the ring formed in the housing; and after said step of affixing, reforming at least a portion of the cylindrical wall adjacent the more open end to reduce a diameter thereof and create an outlet from the housing for attachment to an automobile fuel system.
