Motorcycle fuel system with two injectors positioned in the intake air passage

A vehicle which supplies a fuel stored in a fuel tank to an air-intake passage through which intake-air flows, the intake-air being supplied to an engine which generates driving power for allowing the vehicle to travel, the vehicle comprising:

• a first injector which injects the fuel into the air-intake passage;
• a second injector which is disposed to be apart from the first injector along a flow direction of the intake-air flowing through the air-intake passage and injects the fuel into the air-intake passage;
• a fuel pump which discharges the fuel from the fuel tank;
• a first fuel tube, a first end of which is connected to the fuel pump;
• a second fuel tube, a first end of which is connected to the second injector;
• and
• a connector which is connected to a second end of the first fuel tube, a second end of the second fuel tube, and the first injector, and distributes the fuel which has flowed through the first fuel tube, to the second fuel tube and the first injector,
• wherein the connector is firmly coupled to the first injector,
• wherein at least one of the first fuel tube and the second fuel tube is connected to the connector in such a manner that at least one of the first and second fuel tubes is relatively rotatable in a circumferential direction of the first fuel tube, with respect to the connector,
• wherein the first fuel tube and the second fuel tube are arranged in series, the first and second fuel tubes being spaced apart in a forward and rearward direction and longitudinally extending in the forward and rearward direction, and
• wherein the first end of the first fuel tube is located forward of the connector, and the first end of the second fuel tube is located rearward of the connector.
