PURPOSE:To check any possible pulsation in fuel to the full as well as to reduce a variation in a fuel injection quantity by forming a fuel pipe, conducting the fuel to an injector from a fuel pump into an inverted U-shaped form, and installing a fuel filter being interposed in this fuel pipe in and around an inner bottom plate of a fuel tank. CONSTITUTION:A fuel pump 74 is attached to a crankcase, while a fuel pipe 83 leading to an injector 64 from this fuel pump 74 is bent into a nearly inverted U-shaped form at side view and the length is sufficiently lengthened, while a fuel filter 80 being interposed in the point midway in this fuel pipe 83 is housed in the inner part of a fuel tank 50 and is attached to the inner bottom plate. Accordingly, since fuel is passed through the sufficiently lengthened fuel pipe 83, the pulsation is well absorbed. Especially the fuel filter 80 is attached to the inside of the fuel tank 50, so that this filter 80 is made enlargeable in size and, what is more, a fuel pulsation absorbing effect becomes yet larger. Moreover, since the fuel pipe 83 is made by a rubber tube of at least a part of it, fuel pulsation becomes yet smaller owing to the elasticity.
