ABSTRACT:
A fuel tank and filler system for an internal combustion engine includes a fuel tank, a filler pipe extending into the fuel tank, and a check valve comprising a collapsible, normally open tube secured around the outlet of the fuel filler pipe within the tank. Fuel entering the tank passes through the filler pipe and collapsible tube unimpeded. The collapsible tube has sufficient flexibility, however, to collapse upon itself in the event that fuel begins to flow outwardly through the filler pipe, thereby preventing fuel from leaving the tank through the filler pipe.
