A two-wheeled vehicle includes a frame having a front frame portion, a mid-frame portion, and a rear frame portion. The mid-frame portion is coupled to the rear frame portion and the front frame portion. The vehicle further includes a plurality of ground-engaging members for supporting the frame. The front frame portion is removably coupled to the mid-frame portion with a plurality of frame members extending between the front frame portion and the mid-frame portion.

A fuel supply device includes a sub-tank, a pump unit, a jet pump, and a connection structure connected with the pump unit and the jet pump. The connection structure has a guide part that is provided to the pump unit and guides the pressurized fuel toward the bottom in an axial direction, a pressurizing part that is provided to the jet pump and is fitted to the guide part from a side of the bottom in an axially slidable manner, to which the pressurized fuel is guided from the guide part, a shock-absorbing member that has a low spring constant that is predetermined and mitigates an axial impact between the guide part and the pressurizing part, and a sealing member that has a high spring constant higher than the low spring constant of the shock-absorbing member and radially seals a space between the guide part and the pressurizing part.

A universal fuel-supply assembly is adaptable during manufacturing to be made for use with one of multiple different fuel types (e.g., gasoline or diesel fuel). A method for assembling a fuel-supply assembly includes providing a plate structure configured to be secured to a fuel tank. The plate structure has multiple bosses. According to one example, the method determines whether the fuel-supply assembly is for use as a diesel fuel-supply assembly or as a gasoline fuel-supply assembly. The method provides an opening through one of two different bosses that communicates with both the top side and the bottom side of the plate structure depending on whether the fuel-supply assembly is for use as a diesel fuel-supply assembly or a gasoline fuel-supply assembly.

To provide a component mounting structure for a fuel tank capable of suppressing an increase in the weight of the tank body and reducing the weight and thickness of the fuel tank component, the component mounting structure includes: a tank body (2) provided with an oblong opening (2a); a pump module (3) serving as a tank component mounted to the tank body (2); a flange (5) that is provided to the pump module (3) so as to project out from an outer surface of the pump module (3), has an oblong contour larger than the opening (2a) and having a minor dimension (W2) smaller than a major dimension (L1) of the opening (2a), and is placed inside the tank body (2) through the opening (2a) with an edge thereof opposing the tank body (2) over an entire circumference; a sealing member (7) placed between the tank body (2) and the flange (5); and a fastening member (8b•9, 11•12) that holds the pump module (3) to the tank body (2) while compressing the sealing member (7) via the flange (5).

A fuel supply device includes a cover member which is attached to an opening of a fuel tank, a pump unit comprising a pump, and a connecting portion for connecting the cover member and the pump unit. The pump unit is connected to the connecting portion so as to be relatively movable to the cover member. When the fuel supply device is attached to the fuel tank, an engagement portion provided at a lower portion of the pump unit abuts the connecting portion such that via the engagement portion the connecting portion presses the pump unit against the fuel tank.

In a structure for installing a fuel pump in a fuel tank, in which the fuel pump is attached to the fuel tank by clamping a flange portion of a pump case of the fuel pump between the fuel tank and a retainer fastened to the fuel tank, an interference portion is formed integrally with an inner peripheral edge of the retainer while being overhung inward in a radial direction, the interference portion being capable of interfering with any one of protruding portions when a relative position in a peripheral direction of the retainer with respect to the flange portion is set at a non-normal position, and a non-normal surface of opposite surfaces of the retainer is faced to the flange portion.

An in-tank fuel pump assembly may have a mounting flange with a plurality of first couplings, a fuel pump, a carrier connected to the fuel pump, a plurality of second couplings on at least one of the carrier and the fuel pump, and a plurality of supports each connected to one or the first and second couplings to locate the pump relative to the mounting flange.

A fuel supply device includes a cover member attached to an opening of a fuel tank, a pump unit including a pump, and a connecting portion which connects the cover member and the pump unit. The pump unit is connected so as to be relatively movable with respect to the connecting portion when a connecting shaft which is formed as part of one of the connecting portion or the pump unit, is inserted into the connecting hole formed as part of the other of the two. The connecting hole has an elongated hole portion that allows the connecting shaft to move in the upward and downward directions, and allows the pump unit to be relatively movable with respect to the connecting portion. The pump unit includes an engagement portion abutting a lower terminal end of the connecting portion when the fuel supply device is attached to the fuel tank.

A valve case mounting structure includes a mount base and a valve case. The mount base includes a valve case support portion and a retainer piece having a first engagement opening and a second engagement opening. The valve case includes an engaging projection portion, and a holder portion. When the engaging projection portion is positioned at a front end side of the first engagement opening, the retainer piece does not reach the holder portion. When the engaging projection portion is moved from the front end side of the first engagement opening toward the second engagement opening, a front end portion of the retainer piece is inserted into the holding space before becoming unable to be inserted into the holder portion.

A fuel tank includes a tank main body having an opening, a pump unit mounted to a mounting position on a bottom of the tank main body through the opening and having a fuel pump and a pump retaining member retaining the fuel pump and, and a guide means configured to guide the pump unit from an opening side of the tank main body to the mounting position on a bottom side of the tank main body. The guide means includes a guide rail provided on the tank main body and a slider provided on the pump unit. The slider is configured to be slidably engaged with the guide rail.
