ABSTRACT:
A fuel filling assembly for liquid fuel tanks, especially on boats or the like, includes a fill tube adapted for mounting through a deck and a closure cap preferably hinged over the fill tube opening for selective opening and closing. Preferably, a positioning member allows the closure cap to be mounted in various positions with respect to the fill tube to accommodate various mounting locations on a boat. The fill tube may be angled or straight to further accommodate varied mounting positions. In one version, a separate vent tube joins the fill tube to provide continuous fuel tank venting, pressure equalization and return of fuel overflow to the fuel tank in case of tank overfill. In the vented version, a rigid shield on the closure cap extends over the opening to a vent passageway through the cap to restrict the escape of liquid fuel in the event of fuel surge due to extreme boat movements or the like when the closure cap is closed. The vent passageway is preferably tortuous to restrict ingestion of water or other contaminants and a baffle is mounted over the vent tube opening to prevent expulsion of fuel through the fill tube opening during tank filling when the closure cap is in open position. The positioning member and angled or straight fill tube may also be included in the vented version.
