Abstract: An exemplary system for monitoring and controlling evaporative emissions for a vehicle includes a first fuel vapor adsorption canister, a second fuel vapor adsorption canister, a first passage from the fuel supply to the first canister, a second passage from the first canister to the canister, the second passage including a first valve selectively actuatable from a first position to a second position, a third passage from the first and second canisters for venting the first and second canisters, a fourth passage connecting the second canister to the third passage, and a controller electrically connected to the first valve. Fuel vapor is routed to the first canister when a first condition is not satisfied and fuel vapor is routed to the second canister when the first condition is satisfied.

Abstract: A fuel tank system includes a fuel tank and a fuel pump assembly arranged in the fuel tank and including a fuel pump and a vacuum source. A fuel tank venting system includes a first vent valve arranged in the fuel tank. A storage vessel is arranged in the fuel tank and in fluid communication with the first vent valve. A first fluid line arranged in the fuel tank connecting the storage vessel to the vacuum source of the fuel pump assembly. A second fluid line connects the storage vessel to an evaporative emission system.

Abstract: Disclosed herein are liquid containment systems, methods for making such systems, and vehicle fuel storage systems having vapor recirculation capabilities. Presented is a liquid containment system for stowing hydrocarbon-based liquids. This system includes a vapor canister coupled to a liquid container to receive hydrocarbon vapor from the container. A fill conduit coupled to the container has an opening for receiving a fill nozzle. A vapor recirculation transmits vapor from the container to the fill conduit. A multi-stage check valve, which is coupled to the container and recirculation conduit, has a housing and a plunger with a bleed hole. The plunger seats against the housing such that vapor passes from the container through the bleed hole to the fill conduit via the recirculation conduit. Responsive to increased in-tank pressure, the plunger unseats from the housing such that vapor passes through the bleed hole and around the plunger to the fill conduit.
