Disclosed is a fuel supply structure for a filler pipe including the hollow circular cylindrical part having the fuel filler port and the connection opening, the first flap mechanism which is disposed on a side of the fuel filler port of the hollow circular cylindrical part and opens the fuel filler port in response to press by a nozzle, the drain through hole for communication between the inside and the outside of the hollow circular cylindrical part, and the drain hole shutting valve for open and shutting the drain through hole. The drain hole shutting valve is provided with the opening/shutter mechanism including the valve member for shutting the drain through hole in response to an opening operation of the first shutter member.

An indicator disposed proximate a fuel port of the vehicle is disclosed. The indicator comprises a persistent luminescent layer, a first light source, and one or more circuits. The persistent luminescent layer is configured to emit a first color of light. The first light source is configured to emit a charging emission to charge the persistent luminescent layer. The one or more circuits are configured to selectively activate one or more portions of the first light source such that the persistent luminescent layer is charged and illuminates the indicator in the first color.

A vehicle has a frame defining a cockpit area. The frame has a roll cage disposed over the cockpit area. The vehicle has driver and passenger seats, an engine connected to the frame, and a plurality of ground engaging members operatively connected to the frame, at least one ground engaging member of the plurality of ground engaging members being operatively connected to the engine. The vehicle also has a fuel tank assembly including a fuel tank connected to the frame. The fuel tank is forward of the seats and at least a portion of the fuel tank is disposed under the roll cage.

A non-metallic fuel tank includes a non-metallic tank body, at least one coupling device or mounting system for coupling the non-metallic tank body to a bed of a truck or to a trolley, and a fuel fill opening. A grounding wire may be coupled to the non-metallic tank as well as a fuel line connector which is also coupled to the existing fuel system of a truck. A mounting system for a non-metallic fuel tank includes two rear toe clamps and two front mounting assemblies which include a front mount base and an angle iron coupled together. A portable fuel tank includes a non-metallic tank body and a trolley coupled to the tank body. The trolley includes a base, a mounting system for coupling the non-metallic tank body and the base, at least one handle and at least one wheel.

An advancing/retreating movement mechanism 1 of an advancing/retreating member includes: a lifter 3; a coil spring 5; a lock pin 7 that limits the movement of the lifter 3; a case 2 that accommodates the lifter 3 and the coil spring 5; an advance/retreat position control mechanism 9 that controls an advance position, a retreat position, and a reciprocating movement of the lifter 3; and a receiving seat 11 that receives the coil spring 5 so that the lifter 3 is biased. The receiving seat 11 is arranged in a rearward position side of the lifter 3. An engaging part 27a engaging the lock pin 7 is arranged to the lifter 3. When the lifter 3 moves to the retreat position, the engaging part 27a moves to a rearward side beyond the receiving seat 11 and moves to a position where the engaging part 27a can be engaged with the lock pin 7. Therefore, the size of the advancing/retreating member in a protruding/withdrawing direction can be made small.

A fuel separation system includes a fuel separator configured to receive a fuel stream and separate the fuel stream, based on a volatility of the fuel stream, into a vapor stream defined by a first auto-ignition characteristic value and a first liquid stream defined by a second auto-ignition characteristic value, the second auto-ignition characteristic value greater than the first auto-ignition characteristic value; and a heat exchanger fluidly coupled between a fuel input of the fuel stream and the fuel separator, the heat exchanger configured to transfer heat from the vapor stream to the fuel stream, and output a heated fuel stream to the fuel separator and a second liquid stream defined by the first auto-ignition characteristic value.

A vehicle includes a motor, a power converter, a fuel tank, and a three-phase line. The motor moves the vehicle. The power converter is connected to the motor. The power converter is configured to convert electric power and to supply the converted electric power to the motor. The fuel tank is disposed between the motor and the power converter. The fuel tank has a tank bottom on a side of a bottom of the vehicle. The tank bottom has a recess. The three-phase line is provided in the recess. The motor is electrically connected to the power converter via the three-phase line.

An indicator disposed proximate a fuel port of the vehicle is disclosed. The indicator comprises a persistent luminescent layer, a first light source, and one or more circuits. The persistent luminescent layer is configured to emit a first color of light. The first light source is configured to emit a charging emission to charge the persistent luminescent layer. The one or more circuits are configured to selectively activate one or more portions of the first light source such that the persistent luminescent layer is charged and illuminates the indicator in the first color.

A fuel vapor processing apparatus may include a canister. A negative pressure applying device for applying a negative pressure to the canister may be disposed in a purge passage communicating between the canister and an intake pipe of an engine. A pressure adjusting device may be disposed in a portion of the purge passage communicating between the fuel tank and the negative pressure applying device.
