A vent apparatus includes a tank mount made of a weldable plastics material and a fuel systems component such as a valve assembly. The valve assembly includes a valve housing made of a non-weldable plastics material and a valve movable in a valve chamber formed in the valve housing to open and close an aperture leading to a venting outlet. The tank mount supports the valve housing in a position in a mounting aperture formed in a fuel tank. The valve housing is made by injecting non-weldable plastics material into a mold containing the pre-molded tank mount.

1. A method of forming a vent apparatus adapted to be coupled to a fuel tank, the method comprising the steps ofproviding a tank mount made of a weldable plastics material and adapted to be welded to an exterior surface of a fuel tank including the steps of forming a tank mount mold to include an annular tank mount mold cavity having an L-shaped cross section and injecting a weldable plastics material into the annular tank mount mold cavity to produce a ring-shaped tank mount having an L-shaped cross section including an annular foot including a downwardly facing bottom surface adapted to be welded to an exterior surface of a fuel tank to support the valve housing in an aperture formed in the fuel tank and an annular arm coupled to the annular foot and arranged to extend radially inwardly and include an inner rib and injecting a non-weldable plastics material into a valve housing mold cavity containing the tank mount to overmold the tank mount with the non-weldable plastics material to produce a valve housing having a venting outlet arranged to communicate with a valve chamber formed in the valve housing and arranged to extend above the tank mount and including the steps of forming a valve housing mold to include an inner rib encapsulation portion surrounding the inner rib and filling the inner rib encapsulation portion with non-weldable plastics material to encapsulate the inner rib to mechanically couple the valve housing to the ring-shaped tank mount.
