The present invention relates to an anti-theft device for fuel tanks, wherein the anti-theft device comprises a pipe to be secured to a fuel inlet, wherein the pipe comprises attachment means at its upper portion, furthermore the pipe comprises at least one opening disposed in the side wall of the pipe, wherein the pipe is closed at a lower portion and that said pipe accommodates a substance, wherein said substance is adapted, in the event of a fuel theft attempt, to be carried with the fuel into the pump used during the theft attempt and thereby prevent continued pumping with it, and that the substance is further adapted to be incapable of leaking into the actual fuel tank.

A filler pipe includes a retainer capable of retaining a fuel filler gun inserted through a fuel filler opening, and a pipe main body connecting the retainer and a fuel tank. The retainer has a stopper limiting the insertion of the fuel filler gun. A flow guide that guides the flow of fuel is provided on the downstream side of the stopper with respect to the flow direction of fuel supplied from the fuel filler gun. The flow guide has a guide portion extending at an angle with respect to the flow direction of fuel.

A fuel supply system includes a filler neck that is provided in a filler neck body formed in a tubular shape and has a pipe connection structure. A first member is formed separately from the filler neck. A second member is formed separately from the filler neck to be different from the first member. The first member and the second member are engaged with each other. At least one of the first member and the second member includes a protective portion that is configured to cover at least part of the pipe connection structure in a state that the first member and the second member are engaged with each other and positions of the first member and the second member are fixed relative to the filler neck. This configuration suppresses damage of the pipe connection structure that is connected with the filler neck in the fuel supply system.

A fuel tank for a motor vehicle. The fuel tank includes a tank having an external casing having an opening and a forming zone in a region about the opening, the forming zone having a first forming zone region that is deformed in comparison to a shape of the external casing surrounding the forming zone and a second forming zone region on a periphery of the opening that is deformed greater than the deformation in the first forming zone region. The fuel tank also includes a filler neck for filling the tank, the filler neck leading into an opening of the external casing and being welded to the external casing by way of a weld seam that is accessible from outside the tank, the filler neck in the region of the opening being deformed greater than the deformation than the deformation of the second forming zone region.

Systems, methods, apparatuses, and computer program products are provided for determining carbon emissions of one or more vehicles. For instance, in one example embodiment, an apparatus may calculate miles traveled by the vehicles along a predefined route and may calculate a fuel usage of the vehicles for traveling along the route to obtain one or more fuel values. The apparatus may also analyze data indicating the miles traveled and the fuel values to determine fuel efficiency values corresponding to the vehicles traveling the route. The apparatus may also determine an estimate of an amount of carbon emissions for each of the vehicles based in part on applying at least one carbon emission value to respective fuel values associated with corresponding determined fuel efficiency values.

A fuel filler adapter has a hollow body having a base end with a flange extending outwardly therefrom, and a forward end, and has a length of between 0.5 inch and 2.5 inches. A bore extends through the body at an angle of between 2.5 and 15 so that the adapter can be fitted onto a fuel nozzle. Fueling spitback is prevented by a helical fuel path which does not block air from venting from a fuel tank. Air venting from the fuel tank exits through the fuel filler adapter via one or more venting channels.

A refueling retainer comprises a body portion of a tubular shape inserted into and arranged at a fueling-side end portion of an inlet pipe through which fuel is introduced to a fuel tank. The body portion comprises at a leading end portion thereof: a tapered portion, which is an inner peripheral surface of the leading end portion inclined radially inward toward a leading end of the body portion; and a claw portion that projects from the leading end of the body portion in an inwardly bent manner.

A fuel filler tube housing assembly constructed in accordance to one example of the present disclosure includes a fuel filler neck and a filler extension tube. The fuel filler neck housing includes a first mounting structure operable to support a check valve. The fuel filler extension tube is fixed to the fuel filler neck housing and has a second mounting structure substantially similar to the first mounting structure and thereby also operable to support the check valve.

A capless filler neck closure for use with a vehicle fuel tank filler neck is disclosed. The capless filler neck closure includes an outer dust cover and an inner closure door each movable from a closed position to an opened position in response to insertion of a fuel nozzle into the capless filler neck closure for refueling of an associated vehicle fuel tank.
