Claim:
A vehicle fuel tank assembly comprising: a fuel tank ( 31 ) mounted on a saddle-riding type vehicle ( 1 ) in an inclined attitude in a front-to-rear direction of a vehicle and having a flat shape elongated in the front-to-rear direction; and a fuel pump unit ( 35 ) installed in the fuel tank ( 31 ) by inserting the fuel pump unit into the fuel tank through a bottom wall ( 31 h ) of the fuel tank; wherein the fuel pump unit ( 35 ) includes a main body ( 37 ), a support body ( 38 ) extending from an upper part of the main body ( 37 ) in a longitudinal direction of the elongated fuel tank ( 31 ), and a fuel level gauge ( 39 ) supported and extending on the support body ( 38 ); wherein the fuel level gauge ( 39 ) includes a fuel level gauge body ( 40 ), a float arm ( 41 ) pivotally supported at its proximal end ( 41 a ) by the fuel level gauge body ( 40 ) for up and down swinging movement, and a float ( 42 ) supported on a free end ( 41 b ) of the float arm ( 41 ); and wherein the float arm ( 41 ) extends in the longitudinal direction of the fuel tank ( 31 ) and is set to take a highest swing position in an intermediate height level of the fuel tank ( 31 ); and wherein the support body ( 38 ) is formed with a cutout ( 38 b 3 ) in a lower edge thereof, and the cutout ( 38 b 3 ) has a first width (W 1 ) in the direction in which the support body ( 38 ) extends, and a second width (W 2 ) in a vertical direction perpendicular to the direction in which the support body ( 38 ) extends, the first width (W 1 ) being greater than the second width (W 2 ).
