A fuel supply system of a vehicle is provided with a fuel tanksupported on a vehicle at a level equal to or lower than that of the carburetorsandcombined with an engine. A vacuum fuel cut valveis placed on the upper surface of the fuel tank. A pulse-driven fuel pumpis disposed near the vacuum fuel cut valveon the upper surface of the fuel tank. The vacuum fuel cut valvehas a fuel inlet portconnected to a fuel suction pipe, a fuel outlet pipe, and a vacuum chamber connected to an intake pipeconnected to the cylinderof the engine. The pulse-driven fuel pumpis provided with a fuel suction pipeconnected to the fuel outlet pipeof the vacuum fuel cut valve. When a negative pressure pulse is applied to the vacuum fuel cut valve, the vacuum fuel cut valveopens to supply fuel to the carburetorsand

Fuel supply system of vehicle

An exhaust pipe suitable for a personal watercraft which can reduce exhaust noises, prevent a transom board from being made dirty by an exhaust gas and avoid exposing a rider trying to get onto a deck to the exhaust gas stream directly, the exhaust pipe being provided above a water line of a transom board for discharging an exhaust gas behind the personal watercraft, the exhaust pipe projects from the transom board rearward and has at least a rear portion curved downward. Consequently, an opening face provided on a rear end of the exhaust pipe is oriented obliquely rearward with respect to a water surface as seen from a side of the personal watercraft.
