A cover assembly and method for a vehicle fuel pump includes a cover base secured in a fixed position relative to the vehicle fuel pump and a flexible cover connected to the cover base and positioned by the cover base to inhibit water access to the vehicle fuel pump. The method includes securing the cover base in a fixed position relative to the vehicle fuel pump, connecting the flexible cover to the cover base, and positioning the flexible cover with the cover base to inhibit water access to the vehicle fuel pump.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump is capable of pressurizing the fuel to pressures suitable for use in fuel injection type engines. A resiliently deformable in-tank fuel filter may be coupled to the pump.

A fuel pump cover includes a first cover member and a second cover member. The first cover member has an attachment flange configured to attach to a surface of a fuel tank, a cover part coupled to the attachment flange and configured to cover a first fuel pump outlet to a fuel pump, and an attachment feature. The second cover member is configured to be removably attached to the attachment feature, and configured to cover a second fuel pump outlet to the fuel pump.

A coupling stay includes a support inner peripheral surface extending along a rotational axis and providing radial support to a rotatable shaft portion of a pump unit, which extends along the rotational axis. A support lateral surface extends in a longitudinal direction and provides thrust support to the pump unit. The support inner peripheral surface extends from the support lateral surface in the transverse direction. A lock claw projects from the coupling stay. A lock projection projects from the pump unit and is operable to lock rotation of the pump unit relative to the coupling stay about the rotational axis upon fitting of the lock projection between the support lateral surface and the lock claw. A height of a contact part of the lock projection, which contacts the support lateral surface, is limited to be equal to or lower than the rotational axis.

A connection ring is provided for removable attachment of a fuel supply unit on a fuel tank. The connection ring has a ring upper side, at least one attachment elevation which protrudes from the ring upper side, and at least one tool engagement region. The tool engagement region is constructed such that a torque from a tool can be transmitted onto the connection ring. At least one portion of the tool engagement region and one portion of the attachment elevation are at an equal distance from the center of the connection ring in the radial direction from the center.

A pump assembly for a fluid tank extends along a longitudinal axis and includes a cover at an external end, the cover including a flange that extends radially outward of the longitudinal axis, an insertable end opposite the external end along the longitudinal axis, and a rotatable arm that is flexible such that, when the rotatable arm is resiliently bent such that the rotatable arm has a radial extent, from the longitudinal axis, that is less than the flange, the sender assembly is in a compact state in which the insertable end and the flange would be able to move straight along the longitudinal axis, which is coaxial with a center axis of an opening of the fluid tank, from a position where the insertable end initially enters the opening to a position where the flange engages the fluid tank.

A two-wheeled vehicle includes a frame assembly, a plurality of ground-engaging members for supporting the frame assembly, and a cooling assembly positioned below a head portion of the frame assembly and intermediate vertically-extending frame tubes of the frame assembly. A lower end of the cooling assembly is coupled to a lower end of the vertically-extending frame tubes, and an upper end of the cooling assembly is frictionally retained at an upper end of each of the vertically-extending frame tubes.

A fuel supply device includes a pump unit with a fuel pump that has a rotary body rotating about a rotary shaft and a load receiving portion, configured to receive the load of the pump unit. A connecting portion is provided for connecting the pump unit to the load receiving portion such that the pump unit is suspended by the load receiving portion. The connecting portion is disposed so as to extend across a virtual plane which is perpendicular to the rotary shaft for the rotary body of the fuel pump and passes through the center of gravity of the pump unit.

A displacement amount of an apex of a small diameter part of a coupling shaft portion, which is required to displace the apex of the small diameter part placed in an engaging hole section of a complex hole to a limit point, is defined as a limit displacement amount while the limit point is an intersection between the engaging hole section and an insertion hole section of the complex hole. A projection is formed at a stopper piece as a displacement-amount limiting portion that limits the displacement amount of the apex to an amount, which is equal to or smaller than the limit displacement amount, through contact of the projection against an inner wall surface of the complex hole, which is opposed to the projection.

A sender assembly that has a compact state, which may allow a pump assembly including the sender assembly to be easily inserted into an opening of a fluid tank. For example, the pump assembly may be insertable into the opening of the fluid tank while a longitudinal axis of the pump assembly remains coaxial with the opening. When in the compact state a rotatable arm and a float of the sender assembly may be entirely within or deformable to be within a predetermined envelope that has a radial extent less than the opening of the fluid tank to allow the sender assembly to be inserted straight into the opening. The predetermined envelope may be coaxial with the longitudinal axis and have a cross-section transverse to the longitudinal axis that matches the opening of the tank.
