A sender gauge adaptor includes an adaptor body pressed against a bottom wall of a fuel tank by a spring. The adaptor body includes a suction inlet part having a hollow cylindrical shape that opens downward. Recesses allowing fluid communication between the interior and the exterior of the suction inlet part and projection parts having a polygonal-shaped lower surfaces are alternately arranged in the circumferential direction along a lower end of the suction opening. The adaptor body includes a seat part in surface contact with the bottom wall of the fuel tank at a position below the lower surfaces of the projection parts.

A work vehicle including a tank (31,131) formed so as to extend from a rear part of a vehicle body toward a center, wherein the tank includes: a first storage tank (32) located on the rear side of the vehicle body, and stores stored fluid (9); a second storage tank (34) located on a side close to the center in the front-rear direction of the vehicle body, and stores the fluid; a partition part (36) that separates the first storage tank and the second storage tank; a discharge member (49) that has a discharge opening (49a) extending and opened inside the second storage tank, and discharges, from the second storage tank, the fluid stored in the second storage tank; and a hollow tube member (60) that has a first end communicated with the first storage tank through the partition part so as to enable the stored fluid to flow, and a second end having a hollow tube opening (62) extending and opened toward the center of the vehicle body inside the second storage tank, wherein the hollow tube opening of the hollow tube member is located on the central side of the vehicle body with respect to the discharge opening of the discharge member.

A work vehicle including: a drive device that has an internal combustion engine for driving a vehicle body; a first tank for storing fuel to be supplied to the internal combustion engine; and a second tank for storing fuel to be supplied to the internal combustion engine; wherein the first tank is disposed in front of or behind the drive device, and the second tank is disposed below the drive device so as to be separated from the first tank by a predetermined distance.

A dual reservoir fuel tank, wherein the fuel tank comprises a main fuel reservoir having an inner wall and an outer wall that define a main reservoir chamber, and an auxiliary fuel reservoir connected to a bottom of the main fuel reservoir. The dual reservoir fuel tank additionally includes a fuel retention lip structured and operable to retain fuel within the auxiliary reservoir chamber when the dual reservoir fuel tank is disposed at an angle.

Systems and methods for operating a fuel system that includes two separate fuel tanks are disclosed. In one example, fuel may be purged from a fuel rail in response to Reid vapor pressure of a fuel so that engine starting may be improved. A fuel with a higher Reid vapor pressure may be pumped into the fuel rail when the engine is expected to be cold started.

The present invention relates to a method for controlling a fuel tank arrangement (100) connected to a prime mover (101) for propulsion of a vehicle. More particularly, the fuel tank arrangement (100) comprises a first (102) and a second (104) fuel tank connected to the prime mover of the vehicle.

Provided is a fuel tank made of resin, including: a fuel tank body that is enclosed by a bottom wall, side walls, and an upper wall, the fuel tank body including a first storage portion, a second storage portion, and a coupling portion, the coupling portion communicating an upper portion of the first storage portion and an upper portion of the second storage portion; a pump module disposed in the first storage portion; an open portion formed in the first storage portion; a strut provided in the first storage portion; a separator provided on the strut; a suction portion disposed in the second storage portion; a fuel transfer line that communicates the suction portion to the pump module; a holding portion and a provisional holding portion provided at the separator, the provisional holding portion being configured to removably hold the extra-length portion of the fuel transfer line.

A work vehicle including: a drive device that has an internal combustion engine for driving a vehicle body; a first tank for storing fuel to be supplied to the internal combustion engine; and a second tank for storing fuel to be supplied to the internal combustion engine; wherein the first tank is disposed in front of or behind the drive device, and the second tank is disposed below the drive device so as to be separated from the first tank by a predetermined distance.
