A fuel cell vehicle mounted with a fuel gas tank in an underfloor of the vehicle. The fuel cell vehicle includes: a floor that has a projecting portion projecting upward in a height direction of the vehicle and extending along a front and rear direction of the vehicle; a fuel gas tank arranged under the projecting portion in the height direction of the vehicle and fixed to the floor; and an undercover arranged under the fuel gas tank in the height direction of the vehicle. The undercover has a fixation protruded portion that projects upward in the height direction of the vehicle in a side of the fuel gas tank in a width direction of the vehicle, and being fixed to the floor by the fixation protruded portion.

A vehicle can include a longitudinal direction, a traverse direction and a vertical direction that are orthogonal to each other, a pair of front seats, a pair of rear seats, a fuel tank and a canister. The pair of rear seats can be mounted behind the first pair of seats in the longitudinal direction. The fuel tank can be mounted under a first of the rear seats. The canister can be mounted under a second of the rear seats.

A fuel fill tube assembly for an associated vehicle comprises a tubular fill conduit, a receiver attached to the fill conduit, and a bracket mountable to a surface of the associated vehicle, the bracket is configured to be received by the receiver to thereby support the fill conduit relative to the associated vehicle.

A fuel tank assembly includes a fuel tank and a fuel pump module. The module supports a fuel pump that delivers fuel to an engine of a vehicle, and includes a module housing that provides a cavity that receives the fuel pump, a reservoir that is actively filled with excess fuel discharged from a fuel pressure regulator, and a fuel return passageway that directs excess fuel discharged from the pressure regulator to the reservoir. When the fuel tank assembly is inverted, as may occur when the vehicle is operating under certain dynamic conditions, the discharged fuel is retained within the reservoir, and is supplied to the fuel pump inlet via a wicking filter that extends between the reservoir and the fuel pump inlet. As a result, engine stall due to lack of fuel during certain dynamic conditions can be delayed or avoided.
