An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump is capable of pressurizing the fuel to pressures suitable for use in fuel injection type engines. A resiliently deformable in-tank fuel filter may be coupled to the pump.

A system includes a body with a fluid passage therethrough, a first open end, and an opposite termination, a valve positioned within the body and including first and second ends, the valve moving between open and closed positions, the valve being biased into the closed position, and a seal positioned on the second end of the valve, the seal forming the closed position when the valve is biased towards the first open end of the body, and the seal engaging a shoulder formed by the body to retain the valve within the body. The seal is accessible from the termination of the body to allow the valve to be coupled to the body.

A system that includes a vehicle fuel-receiver comprising a port located on a vehicle surface; and an onboard computer programmed to: send a fuel delivery request to an unmanned aerial vehicle (UAV); actuate the port to permit the UAV to deliver fuel; and instruct a communication module to transmit a beacon signal to the UAV.

A vehicle fuel tank assembly includes a fuel tank and an electrically conductive top plate that closes and seals a fuel-fill opening in the fuel tank. The top plate includes electrical dissipation structures and features that allow for electrical charge dissipation of the fuel tank to an external structure such as the vehicle chassis. The dissipation structures include an electrically insulative carrier that is partially embedded in the top plate using an overmolding process, and an electrical conductor that is supported by the carrier. The electrical conductor provides an electrical connection between the top plate and the chassis that is independent of the fuel tank and the fuel tank mounting structure.

A fuel tank filter assembly and fuel system designed to be used as fuel is initially added to a vehicle. A removable, and cleanable filter sock is provided comprised of mono filament capable of straining micro particles. A pressure release locking cap is also provided. The filter sock allows fuel to flow at a normal rate while still catching and thereby removing unwanted debris.

In a saddled vehicle, an internal combustion engine is disposed below a fuel tank and a riding seal disposed behind the fuel tank. A fuel pump is supported by a front body frame that suspends a front wheel, the fuel pump being disposed at a position where at least part of the fuel pump overlaps with the front wheel as seen in a side view. The fuel tank is supported on an upper frame member that configures part of the body frame. A protection member is extended between the upper frame member and the front body frame, and passes a front of the engine body as seen in a side view. A fuel suction pipe line is covered by the protection member from an outer lateral side and locked to the protection member, the fuel suction pipe line sucking fuel form the fuel tank to the fuel pump side.

A computer that includes a processor and memory which stores instructions executable by the processor. The instructions include: initiate, from a vehicle, a fuel delivery request for fuel delivery by an unmanned aerial vehicle (UAV); in response to the initiation, instruct a communication module in the vehicle to transmit a beacon signal to enable the UAV to locate the vehicle; and coordinate a docking procedure between the UAV and the vehicle to receive fuel from the UAV.

A fuel tank includes a body defining a fuel holding cavity therein, a spill box attached to the body, a fill port for fluid communication with the fuel holding cavity, the fill port being disposed within the spill box, and an accumulation box disposed on a top of the body and defining a fuel overflow cavity therein that is in fluid communication with the fuel holding cavity. Methods of retrofitting a fuel tank and venting a fuel tank are also described.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.

A side-by-side off-road vehicle has a frame defining at least in part a cockpit area, and a power pack area being disposed rearward of the cockpit area. The vehicle has driver and passenger seats connected to the frame and disposed in the cockpit area on first and second sides of a longitudinal centerline of the vehicle. The vehicle further has a power pack connected to the frame and disposed at least in part in the power pack area. The power pack includes an internal combustion engine, an exhaust pipe, a muffler, and a fuel vapor containment system including a fuel evaporation canister. The fuel evaporation canister is disposed forward of the muffler, and at least a majority of the exhaust pipe and the fuel evaporation canister being disposed on opposite sides of the longitudinal centerline of the vehicle.
