Patent ID: 8763646

Claim:
A fuel tank comprising: a thermoplastic tank wall having an exterior filling connection; an interior venting apparatus comprising: a cylindrical connection portion; a first pipe extending outward from the cylindrical connection portion, the first pipe comprising: a deformable cylindrical section proximal to the cylindrical connection portion; a distal line extending outward from the deformable cylindrical section of the first pipe to a venting valve at a distal end; a proximal line extending from the connection portion to the deformable cylindrical section of the first pipe; wherein the distal line of the first pipe is distal to the cylindrical connection portion and the proximal line of the first pipe is proximal to the cylindrical connection portion; a second pipe extending outward from the cylindrical connection portion, the second pipe comprising: a deformable cylindrical section proximal to the cylindrical connection portion; a distal line extending outward from the deformable cylindrical section of the second pipe to a venting valve at a distal end; a proximal line extending from the connection portion to the deformable cylindrical section of the second pipe; wherein the distal line of the second pipe is distal to the cylindrical connection portion and the proximal line of the second pipe is proximal to the cylindrical connection portion; wherein the deformable cylindrical section of the first pipe and the deformable cylindrical section of the second pipe are both a first polymer having a Shore A hardness of less than 70; wherein the distal line of the first pipe, the distal line of the second pipe, the proximal line of the first pipe, and the proximal line of the second pipe are all a second polymer having a Shore A hardness of greater than 70.
