Claim Text:
1. An improved vent for a fuel tank having a tank top wall defining an access aperture, comprising: a canister having a bottom wall and a side wall extending from said bottom wall to define an internal volume having an open top; a mounting for securing said canister to an interior surface of said tank top wall with said open top of said a canister adjacent to the access aperture defined in the tank top wall; a float valve located within said canister for sealing said open top of said canister; a major vent output pipe interconnecting said internal volume of said canister external to the fuel tank; a vent aperture defined in said canister providing a fluid path below said float valve; a vent pipe extending between a proximal end and a distal end; said proximal end of said vent pipe connected to said vent aperture defined in said canister; and a hanger securing said distal end of said vent pipe proximate to said interior surface of said tank top wall for venting the fuel tank during fuel entering the fuel tank and for enabling fuel entering said distal end of said vent pipe to close said float valve to limit the amount of fuel entering into the fuel tank.
