Abstract
A vehicle fuel supply structure with an improved fuel filter for easy maintenance of the fuel filter. A vehicle fuel supply structure includes fuel in a fuel tank that is sucked by a fuel pump and supplied to a fuel injection valve disposed in a throttle body via a secondary fuel filter adapted to filter the fuel to remove foreign matter therein. A regulator is provided for regulating fuel pressure. The secondary fuel filter, the regulator and the fuel injection valve are connected by fuel pipes. A third fuel filter is installed at least in an inlet side connecting portion between the regulator and a regulator inlet side fuel pipe, of the fuel pipes, on the side where fuel enters the regulator.
