An insert for a fuel vapor valve traps liquid fuel and prevent the fuel from leaking out of the valve. The insert includes a tube and a skirt disposed around the tube. The skirt seals against a portion of the fuel vapor valve, such as against an inner wall of a valve port or on a top portion of the valve to act as a valve cap. The tube and the skirt cooperate with the fuel vapor valve to form a reservoir that traps fuel.

Liquid trap for fuel vapor valve

A fuel tank cap including a vapor storage receptacle and a discriminator that discriminates between liquid fuel and fuel vapor for protecting the vapor storage receptacle from liquid and adsorbent granulated carbonaceous material. A fuel storage system including a fuel tank cap having a vapor storage receptacle is also disclosed.

Fuel tank cap with integrated carbon canister

A small engine fuel tank vapor emission system is described with a separate surge tank having a vapor vent/rollover valve and separate a vapor storage space which may be found in a common housing or remote from the surge tank. The surge tank is located at a level above the fuel tank and is connected to have its inlet receive vapor from the fuel tank. The outlet of the vapor vent/rollover valve is connected to supply vapor purge flow to the engine air inlet either directly or through the storage space, which may be charged with adsorbent.
