(Problem to be Solved by the Invention) By the way, if there is no air guide for the radiator, the hot air that has passed through the radiator will hit the fuel supply device located at the rear intermediate part of the left and right radiators, which will reduce the heat effect. There's a problem. In addition, by providing an air guide to release the warm air to the sides of the vehicle, the running air will only flow into the fuel supply system from the relatively small space between the left and right radiators.
There is a problem of insufficient cooling for the fuel supply system.
