An apparatus for attachment in an aperture of a fuel tank includes a cap member, a mounting portion, and a valve housing. Two or more of the cap member, the mounting portion, and the valve housing include a system of clips and catches or a system of helical threads, which attach the components together. The mounting portion may include a multi-layer laminate to reduce a fuel vapor permeation from the fuel tank. The cap member, the mounting portion, and the valve housing are attached by various steps and methods according to the invention.

1. An apparatus for attachment in an aperture of a fuel tank, the apparatus comprising:a cap member having a vapor-inlet opening, a vapor-outlet opening, and a passageway interconnecting the vapor-inlet opening and the vapor-outlet opening;a mounting portion defining a weldfoot configured for welding to the fuel tank, wherein the mounting portion includes a laminate having multiple layers including a weldable layer, the laminate configured to block a permeation of fuel from about a surface of the fuel tank proximate the mounting portion, the laminate being disposed at least within the weldfoot and configured such that only the weldable layer is welded to the surface of the fuel tank;means for connecting the cap member and the mounting portion together; anda valve housing attachable to the cap member, the valve housing at least partially disposed within an interior of the fuel tank, the valve housing configured for fuel-vapor communication with the interior of the fuel tank and the vapor-inlet opening of the cap member.2. An apparatus for mounting a valve assembly in an aperture of a fuel tank, the apparatus comprising;a cap member having a first helical thread defined thereon and a nozzle, the nozzle defining a vapor-inlet opening, a vapor-outlet opening and a passageway therein;a mounting portion defining a weldfoot and a second helical thread defined thereon, the weldfoot having a multilayer laminate configured to reduce a fuel-vapor permeation from the fuel tank, the weldfoot configured for welding to a surface of the fuel tank, the second helical thread configured for attachment with the first helical thread to attach the cap member and the mounting portion together; anda valve housing attachable to the cap member and at least partially disposed within an interior of the fuel tank, the valve housing configured for fuel-vapor communication with the interior of the fuel tank and the vapor-inlet opening of the cap member.3. The apparatus as in claim 2, wherein the first helical thread defines an engaging surface disposed in a substantially vertical plane.4. The apparatus as in claim 2, wherein the cap member is made from a material selected from the group consisting of HDPE, nylon, POM, PEEK, and combinations thereof.5. The apparatus as in claim 2, wherein the multilayer laminate has a weldable layer, the multilayer laminate being disposed at least within the weldfoot and configured such that only the weldable layer is welded to the surface of the fuel tank.6. The apparatus as in claim 2, wherein the cap member defines a contact surface disposed apart from the surface of the fuel tank and the mounting portion has an opposing surface, the contact surface and the opposing surface configured to halt rotation of the first and second helical threads to attach the cap member and the mounting portion together.7. The apparatus as in claim 2, wherein the valve housing has a third helical thread defined thereon, the third helical thread further defining an engaging surface disposed in another substantially vertical plane substantially parallel to the vertical plane of the engaging surface of the first helical thread, the engaging surface of the third helical thread configured to abut an engaging surface of the second helical thread, the engaging surface of the second helical thread disposed substantially in a third vertical plane substantially parallel to the second vertical plane.8. The apparatus as in claim 2, further including one of an o-ring, a gasket, a sealant and combinations thereof disposed between one of the cap member, the mounting portion, the valve housing and combinations thereof.9. An apparatus for mounting a valve assembly in an aperture of a fuel tank, the apparatus comprising:a cap member having a holding piece, a vapor inlet opening, a vapor outlet opening, and a passageway interconnecting the vapor inlet opening and the vapor outlet opening;a mounting portion defining a weldfoot and a projection piece to be held by the holding piece, the weldfoot configured for welding to the fuel tank, the holding piece and the projection piece cooperable to attach the cap member to the mounting portion; anda valve housing attachable to the cap member, the valve housing at least partially disposed within an interior of the fuel tank, the valve housing configured for fuel vapor communication with the interior of the fuel tank and the vapor inlet opening of the cap member, wherein vertical cross sections of each of the valve housing, the mounting portion, and the member define a helical structure.10. The apparatus as in claim 9, wherein the projection piece is a helical thread.11. The apparatus as in claim 9, wherein the holding piece of the cap member is a complementary helical thread, the holding piece configured for removably capturing the projection piece of the mounting portion.12. The apparatus as in claim 9, wherein the mounting portion includes a laminate having multiple layers including a weldable layer, the laminate configured to block a permeation of fuel from about a surface of the fuel tank proximate the mounting portion, the laminate being disposed at least within the weldfoot and configured such that only the weldable layer is welded to the surface of the fuel tank.
