Fuel tank assembly of vehicle

摘要

A vehicle fuel tank assembly is provided with a fuel tank and a fuel pump unit. The fuel tank is mounted on a saddle-riding type vehicle. The fuel tank has a flat shape elongated in the front-to-rear direction. The fuel pump unit includes a main body, a support body extending from the upper part of the main body in the longitudinal direction of the fuel tank, and a fuel level gauge supported and extending on the support body. The fuel level gauge includes a fuel level gauge body, a float arm pivotally supported by the gauge body, and a float on the free end of the float arm. The float arm extends in the longitudinal direction of the fuel tank and takes a highest swing position in an intermediate level of the height of the fuel tank. The fuel tank assembly enables fuel level detection in a wide range.

1. 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 (31h) 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 (41a) by the fuel level gauge body (40) for up and down swinging movement, and a float (42) supported on a free end (41b) 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 (38b3) in a lower edge thereof, and the cutout (38b3) has a first width (W1) in the direction in which the support body (38) extends, and a second width (W2) in a vertical direction perpendicular to the direction in which the support body (38) extends, the first width (W1) being greater than the second width (W2).
