A fuel system is provided that includes a fuel system frame and in some cases access steps. The frame can be mounted to a vehicle frame rail. Bracket assemblies can be coupled to the fuel system frame at a plurality of positions. The fuel tank can be mounted at neck portions thereof and can be supported on the frame rail between the neck portions, e.g., spaced a distance from the neck portions in a longitudinal direction of the fuel system. The access steps can be non-rectangular to provide a wide stepping portion even if the fuel system includes large tanks. The steps can be directly supported by an outside surface of the tank.

Some of the present apparatuses include a frame defining first and second supports and at least a portion of a rigid tank mount laterally offset from the first and second supports, where the first support is configured to be pivotally coupled to a vehicle such that the frame is movable relative to the vehicle between a first position in which the second support is spaced apart from the vehicle and second position in which the second support is coupled to the vehicle. Some apparatuses include a frame mount having a flange defining a bounded opening configured to receive a fastener and a post extending from the flange and away from the opening, where the first support is configured to be pivotally coupled to the flange via the fastener and the second support is configured to be coupled to the post when the frame is in the second position.

A fuel tank assembly includes a shell defining an opening therein, an access panel connectable to the shell and movable between a closed position where the opening is closed and an open position where the opening is open, and a fuel tank disposed in the shell and slidably engaged with the shell. The fuel tank and the opening are dimensioned such that the fuel tank is slidable out of the shell via the opening when the access panel is in the open position. A generator assembly and a method of servicing a fuel tank of a generator are also described.

A structurally integrated fuel tank and method of assembling is disclosed. The fuel tank may comprise a body and a neck disposed on the body. The neck may be configured to be coupled to an arm of a front frame of a machine. The body may comprise a cover, an endwall and a base. The cover includes a cover hitch that defines an upper pivot bore centered about a pivot axis. The upper pivot bore is configured to receive a pivot fastener about which the fuel tank is pivotable. The endwall may be disposed below and coupled to the cover. The base may be coupled to the endwall, and may include a lower hitch that extends outward and away from the endwall. The neck and the body together define a chamber configured to store fuel. The cover is a top of such chamber.

In the work vehicle, a pair of left and right fuel tanks is distributed into left and right sides of a traveling body. A tank support plate to support the fuel tanks from below is made up of a pair of front and rear transverse frames extended leftward and rightward below the left and right rear frames, and a pair of left and right tank mounting plates on which the front and rear transverse frames are held in a back-and-forth direction on both left and right sides. The left and right fuel tanks are respectively mounted and secured onto the left and right tank mounting plates. A support mount and the front transverse frame are coupled to each other by a coupling bracket.
