Abstract
A trunk mounted fuel tank assembly including a cradle, a fuel tank, and at least one retention strap is disclosed. The cradle includes a back portion and bottom portion with a fuel feed passage that is placed over a surface of a trunk. The fuel tank includes a fuel line that is placed about the back portion and bottom portion of the cradle. The fuel line extends through the fuel feed passage and a passage in the surface of the trunk. The at least one retention strap includes a first leg and a second leg that is placed over a top portion of the fuel tank for retaining the fuel tank to the cradle.
Claims23
A trunk mounted fuel tank assembly, comprising:
- a cradle including a back portion and a bottom portion, wherein the bottom portion includes a fuel feed passage that is placed over and aligned with a correspondingly sized passage in a surface of a trunk;
- a fuel tank including a fuel line, wherein the fuel line extends through the fuel feed passage and the passage in the surface of the trunk;
- and
- at least one retention strap including a first leg and a second leg, wherein said second leg engages a top portion of the fuel tank for retaining the fuel tank to the cradle.
A trunk mounted fuel tank assembly, comprising:
- a cradle including a back portion and a bottom portion, wherein the bottom portion includes a fuel feed passage that is placed over a passage in a surface of a trunk;
- a fuel tank including a fuel line, wherein the fuel line extends through the fuel feed passage and the passage in the surface of the trunk;
- at least one retention strap including a first leg and a second leg, wherein said second leg engages a to portion of the fuel tank for retaining the fuel to the cradle;
- wherein the fuel tank includes an enclosure that encapsulates an outer surface of the fuel tank, wherein the enclosure terminates near a fuel line interface, wherein the fuel line interface extends through the surface of the trunk and out to an underbody of the vehicle;
- and
- wherein the fuel line interface includes at least a pump within the fuel tank, a sealant, and a fuel line.
A trunk mounted fuel tank assembly, comprising:
- a cradle including a back portion and a bottom portion with a fuel feed passage that is placed over a surface of a trunk, wherein the cradle includes a first flange including a key passage and an integral wedge portion that extends from the back portion of the cradle and permits fastening of the cradle to the surface of the trunk by a welded stud including a key portion and wedge-receiving portion that extends from the surface of the trunk, wherein the wedge-receiving portion guides the stud about a channel of the key passage that extends through the wedge portion, wherein the cradle includes a second flange that extends from the bottom portion of the cradle and includes a first fastener passage;
- a fuel tank including a fuel line that is placed about the back portion and bottom portion of the cradle, wherein the fuel line extends through the fuel feed passage and a passage in the surface of the trunk, wherein the fuel tank includes an enclosure comprising a blow-molded high-density polyethylene that conforms to an encapsulates an outer surface of the fuel tank, wherein the enclosure terminates near a fuel line interface that extends through the surface of the trunk and out to an underbody of the vehicle;
- and
- at least one retention strap including a first leg and a second leg that is placed over a top portion of the fuel tank for retaining the fuel tank to the cradle, wherein the second leg is connected to the back portion of the cradle, wherein the first leg includes a second fastener passage that permits a bolt to extend through the first and second fastener passage that connects the at least one retention strap to the cradle and surface of the trunk, wherein the cradle and at least one retention strap comprises stamped steel.
A trunk mounted fuel tank assembly, comprising:
- a cradle including a back portion and a bottom portion, wherein the bottom portion includes a fuel feed passage that is placed over a passage in a surface of a trunk;
- a fuel tank including a fuel line, wherein the fuel line extends through the fuel feed passage and the passage in the surface of the trunk;
- at least one retention strap including a first leg and a second leg, wherein said second leg engages a top portion of the fuel tank for retaining the fuel tank to the cradle;
- wherein the cradle includes a first flange that extends from the back portion that permits fastening of the cradle to the surface of the trunk by a first fastener, wherein the cradle includes a second flange that extends from the bottom portion of the cradle and includes a second fastener passage;
- and
- wherein the second leg is connected to the back portion of the cradle, wherein the first leg includes a first fastener passage that permits a second fastener passage to extend through the first and second fastener passages that connect the at least one retention strap to the cradle and surface of the trunk.
A trunk mounted fuel tank assembly, comprising:
- a cradle including a back portion and a bottom portion, wherein the bottom portion includes a fuel feed passage that is placed over a passage in a surface of a trunk;
- a fuel tank including a fuel line, wherein the fuel line extends through the fuel feed passage and the passage in the surface of the trunk;
- at least one retention strap including a first leg and a second leg, wherein said second leg engages a top portion of the fuel tank for retaining the fuel tank to the cradle;
- wherein the fuel tank includes an enclosure that encapsulates an outer surface of the fuel tank, wherein the enclosure terminates near a fuel line interface, wherein the fuel line interface extends through the surface of the trunk and out to an underbody of the vehicle;
- and
- wherein the fuel line interface includes a forward flow check valve arrangement, wherein the fuel line and a quick connect supply line are intermediately connected by the forward flow check valve arrangement that comprises a body with sealing threads, a threaded weld nut, and fuel line connections, wherein the forward flow check valve arrangement pierces the outer surface of the fuel tank and is sealed by a weld about a bottom perimeter of the threaded weld nut.
