Patent ID: 8720484

Claim:
A fuel system, comprising: a fuel tank including a fuel tank wall forming a fuel retaining chamber, a fuel level indicator circuit coupled to said fuel tank, said fuel level indicator circuit including a fuel level detector, a fuel level indicator, and a fuel line position switch, said fuel level indicator circuit effective for indicating the amount of fuel residing in the fuel retaining chamber, wherein said fuel level detector senses an amount of fuel disposed within the fuel retaining chamber, wherein said fuel line position switch selectively contacts said fuel line for sensing a proper position of said fuel line with respect to the fuel tank, wherein said fuel line position switch electronically disables said fuel level indicator circuit when said fuel line is not properly coupled to the fuel line position switch, wherein the fuel line position switch includes a surface portion corresponding to a portion of a fuel line for permitting the portion of the fuel line to physically contact the surface portion of the fuel line position switch, wherein said fuel line position switch disables said fuel level indicator circuit from operating when said fuel line is not properly coupled to the fuel tank, wherein said fuel line position switch includes a mechanically actuated electrical switch, wherein the fuel line position switch includes: a lever, wherein the lever is movable between at least two positions including an open position and a closed position, wherein the open position is defined by the lever being disengaged from the fuel line, wherein the closed position is defined by the lever being engaged with the fuel line, wherein the lever is biased to the open position when the fuel line is not engaged with the lever, wherein the fuel tank forms an opening that permits the fuel line to contact the lever for overcoming the bias of the lever to change the open position of the lever to the closed position of the lever for re-orientating the fuel line position switch from being electrically opened to being electrically closed.
