An assembly for a fluid tank includes a baffle and a fluid transfer line. The baffle includes a first deflecting surface defining a first part of the tank and a second deflecting surface defining a second part of the tank. The fluid transfer line extends from the first part to the second part and is linked to the baffle by a linkage supported by the assembly. The extension of the fluid transfer line in the first part defines a first portion of the fluid transfer line, and the extension of the fluid transfer line in the second part defines a second portion of the fluid transfer line. The linkage allows for simultaneous rotation of the first portion and the second portion of the fluid transfer line towards a surface including one of the deflecting surfaces.

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 rigid connecting device for connecting the upper and lower surfaces inside an oil tank includes a connecting rod. The upper and lower sides of the connecting rod are each provided with a connecting end surface. The connecting end surface is provided with material-passing hole. The outer surface of the rigid connecting device is covered with high-density polyethylene. The upper and lower surfaces of the oil tank are connected by a connecting rod, and such arrangement is locally applied to areas where the rigidity of the oil tank is poor, so there are more effective space. The part of the rigid connecting rod contacting with the oil fuel is made of high-density polyethylene, so the requirements of strength and anti-corrosion can be satisfied.

Methods and systems are provided for regulating fuel flow in a fuel tank. In one example, a method may comprise fueling a fuel tank by receiving a nozzle into a filler tube which extends into a fuel tank to fuel the fuel tank, and directing fuel through the tube against vanes in a baffle which forms a compartment within the tank. Additionally, the method may comprise enabling the vanes to open so that pressure within the compartment remains below a level which would otherwise cause shut off the nozzle during the fueling.

A method and apparatus for modifying an existing style fuel tank to add a fuel pump and a baffle assembly in the tank comprises removing an existing fuel sending unit from a sending unit opening and cutting an access hole in the top of the tank. Fuel supply and return lines, and electrical connections for the fuel pump are routed through a replacement cap for covering the sending unit opening and not up through the hole created for insertion of the pump and baffle assembly. The baffle assembly includes a cup for holding fuel around and over the fuel pickup connected to the fuel pump. The cup may be formed from a compressible material to allow it to be compressed before insertion into the tank through the access opening or it may be assembled inside of the tank from segments inserted through the access opening.

A multi-vessel reservoir assembly is provided. The multi-vessel reservoir assembly comprises a first fluid vessel, a second fluid vessel, and at least one linkage positioned between the first and second fluid vessels. The at least one linkage serves to maintain the first and second fluid vessels in fixed and spaced-apart relationship relative to one another. The first and second fluid vessels are independent and separately operable.

A fuel tank for a truck, the fuel tank having a fuel tank body with a peripheral wall and end walls that define at least one receptacle to receive a liquid or gaseous medium. At least one baffle is fixedly attached to the inside surface of the peripheral wall via an inner fixing member. An outer fixing member is to fixedly attach the fuel tank body to the chassis of the truck, and is also connected to the inner fixing member through the peripheral wall.

There is provided a fuel tank including: a fuel tank main body enclosed by a floor wall, side walls and an upper wall; and a separator including a strut, a first plate portion in which a first penetrating hole that penetrates in a plate thickness direction is formed, and a second plate portion in which a second penetrating hole that penetrates in a plate thickness direction is formed, the second plate portion sandwiching the strut with the first plate portion and extending in a diametric direction at an opposite side of the strut from a side thereof at which the first plate portion is disposed, wherein at least one of shapes, sizes or numbers of the first penetrating hole and the second penetrating hole is set to be different such that fluid resistances at the first plate portion and the second plate portion are different.

A tank for transporting a liquid is disclosed. In some implementations, the tank includes a carrier having a plurality of compartments, each compartment of the plurality of compartments having an opening for containing one or more baffles. In some implementations, the tank includes a plurality of posts that are securable relative to the tank and configured to support the one or more baffles. In some implementations, the posts are removed from the tank to facilitate installation of the baffles. In some implementations, the posts are rotatable to facilitate installation of the baffles. In some implementations, the tank is a two-piece tank which facilitates access to the one or more baffles.

A multi-vessel reservoir assembly is provided. The multi-vessel reservoir assembly comprises a first fluid vessel, a second fluid vessel, and at least one linkage positioned between the first and second fluid vessels. The at least one linkage serves to maintain the first and second fluid vessels in fixed and spaced-apart relationship relative to one another. The first and second fluid vessels are independent and separately operable.
