Abstract: A reservoir arrangement for use in an automotive fuel tank includes a reservoir body in which fuel is guided and from which fuel is pumped. The reservoir body defines a fuel passage by upwardly depressing its bottom surface and fittingly engaged the depressed surface with a chamber plate. The chamber plate is made of a material whose swelling amount by fuel is larger than that of the reservoir body, thereby causing a tight fit of the chamber plate.

Abstract: A jet pump structure for a fuel tank having first and second chambers therein includes first, second and third fuel pipes all of which are connected to a vacuum chamber provided within the fuel tank. The first pipe returns oversupplied fuel into the vacuum chamber, the second pipe transfers fuel stored in the first chamber into the vacuum chamber, and the third pipe receives the fuel from the first and second pipes and discharge same into the second chamber. A flow guide member is provided within the first pipe, which receives the oversupplied fuel to form same into a swirl flow. The swirl flow is ejected from the first pipe as a jet flow into the vacuum chamber to provide a vacuum therearound within the vacuum chamber. The ejected swirl flow further works to seal the vacuum chamber against the third pipe so that the vacuum generated within the vacuum chamber is prevented from being released through the third pipe to effectively suck the fuel from the first chamber.

Abstract: A filter arrangement disposed in a fuel tank of an automotive vehicle has a flat upper section made of mesh. A lower section made of mesh is joined to the upper section to define a space between the upper and lower sections. The space is filled with fuel filtered by the upper and lower sections and communicates with a fuel pump. The upper and lower sections are different in shape and therefore deform differently under suction due to operation of the fuel pump. This prevents the filter arrangement from collapsing under suction, thereby effectively ensuring a fuel flow passage leading to the fuel pump.

Abstract: A reservoir in which fuel can be collected when only a small amount of fuel remains in the fuel tank, is arranged to support a fuel pump and to be connectable to the lower wall of the tank by a snap action type connector arrangement which is defined between a bracket fixed to the lower wall of the fuel tank and a portion of the reservoir which cooperates with the bracket. The reservoir containing the pump can be manually introduced into the interior of the fuel tank through an opening in the top thereof and maneuvered into engagement with the bracket. The center of gravity of the relatively heavy pump is arranged to be generally over the top of the bracket. When a predetermined strong force is applied to the reservoir in a predetermined manner it can disengage from the bracket.
