According to the invention said connecting device (1) comprises a tubular member (10) It provided to be inserted into the liquid tank (2), said tubular member (10) having a first end portion (100) and a second end portion (101) provided to constitute a swirl pot (4), and a flange (11) located on the external part of the tubular member (10), a surface (110) of the flange (11) being provided to be welded to an external surface of a tank wall (2), the connecting device (1) comprising a connecting means (12) on the first end portion (100) of the tubular member (10), said first end portion (100) being located on the tubular member (10) relative to the flange (11) on the other side of the flange surface (110) provided to be welded to the liquid tank (2), said connecting means (1) being provided for the fixing of the Liquid Delivery Module (3) to the tubular member (10), the second end portion (101) of the tubular member (10) comprising an opening (1010) provided to allow entry of the liquid in the tubular member (10), the first end portion (100) comprising an opening (1000) provided for the insertion of the Liquid Delivery Module (3).

The present invention discloses a dual mode fuel tank leakage detector (100), comprising of an electromechanical valve (1) with a canister port, an engine control unit, pump assembly, a sensor (3) and works in pressure condition by comparing a measured pressure with reference pressure; in case there is leakage then the pressure is not upto the reference pressure within time interval. In case of no leakage, the pressure will be equal/above than the reference pressure, the leakage detector (100) works in vacuum condition by comparing a measured leakage with a reference leakage, in case there is a leakage the measured vacuum is not able to reach to the reference vacuum within a time interval and when there is no leakage, the measured vacuum will be equal or above from the reference vacuum and fuel tank leakage detector (100) enables to monitor leakage detection either in vacuum or pressure conditions.

Methods and systems are provided for a deflector. In one example, a system includes a first engine bay component comprising a deflector with a deflection surface shaped to engage a second engine bay component to rotate the first engine bay component and mitigate contact between the first engine bay component and a third engine bay component.

A motor vehicle tank subassembly for storing and discharging an operating liquid, encompassing a tank having a tank volume, a filling opening a withdrawal opening, and a conveying pump having intake and delivery sides, the intake side connected to the withdrawal opening, a material that forms a pore volume being received in the tank; the material that forms a pore volume, constituting a porous conveying body having a body volume, occupies only part of the tank volume, the porous conveying body embodied to receive liquid stored in the tank in its pore volume utilizing a capillary effect; the porous conveying body having a discharge portion connected to the withdrawal opening such that the withdrawal vacuum at the withdrawal opening brings about in pores of the discharge portion a discharge vacuum that overcomes the capillary effect occurring there; the remainder of the porous conveying body extending away from the discharge portion and the withdrawal opening.

A fuel supply device may include a housing, a fuel pump, a regulator, and an atmosphere communication passage. The housing may include a housing main body in which a fuel storage tank is formed and a lid body that covers an opening part of the housing main body. The fuel pump may feed a fuel that is stored. The regulator may return a surplus fuel to the fuel storage tank while regulating a pressure of the fuel. The atmosphere communication passage may penetrate through from a bottom surface side to an upper surface side of the lid body to communicate an upper space of the fuel storage tank with an outside. A center line of an inlet-passage vertically disposed and a center line of an outlet-side passage vertically disposed may be shifted from each other by a predetermined distance in a horizontal direction.
