Abstract

A serviceable sealed fuel tank includes a tank shell having a first half shell and a second half shell connected to the first half shell. The serviceable sealed fuel tank also includes at least one internal component disposed inside the tank shell between the first half shell and the second half shell. The serviceable sealed fuel tank further includes an inspection tower extending outwardly from the second half shell and being sealed. A portion of the inspection tower is removed to allow access to the at least one component after the first half shell and the second half shell are connected together.

Claims

1. A serviceable sealed fuel tank comprising:

a tank shell having a first half shell and a second half shell connected to said first half shell;

at least one internal component disposed inside said tank shell between said first half shell and said second half shell; and

an inspection tower extending outwardly from said second half shell and being sealed, wherein a portion of said inspection tower is removed to allow access to said at least one component after said first half shell and said second half shell are connected together.

2. A serviceable sealed fuel tank as set forth in claim 1 wherein said inspection tower comprises a side wall extending upwardly and generally perpendicular to said second half shell.

3. A serviceable sealed fuel tank as set forth in claim 2 wherein said inspection tower further comprises a top wall extending generally perpendicular to said side wall and sealing said inspection tower.

4. A serviceable sealed fuel tank as set forth in claim 3 wherein said portion is removed from said top wall to form an opening therein.

5. A serviceable sealed fuel tank as set forth in claim 4 including a sealing cover to cover and seal said opening.

6. A serviceable sealed fuel tank as set forth in claim 5 wherein said sealing cover comprises a base wall and a side wall extending from said base wall.

7. A serviceable sealed fuel tank as set forth in claim 6 wherein said side wall includes a plurality of internal threads.

8. A serviceable sealed fuel tank as set forth in claim 7 wherein said internal threads are self-tapping.

9. A serviceable sealed fuel tank as set forth in claim 7 wherein said sealing cover includes a seal disposed between said base wall and said internal threads.

10. A serviceable sealed fuel tank as set forth in claim 6 wherein said base wall includes an opening extending therethrough and a cover plate disposed adjacent said opening.

11. A serviceable sealed fuel tank as set forth in claim 1 wherein said inspection tower is a monolithic structure being integral, unitary and one-piece.

12. A serviceable sealed fuel tank for a vehicle comprising:

a tank shell having a first half shell and a second half shell connected to said first half shell;

at least one internal component disposed inside said tank shell between said first half shell and said second half shell; and

an inspection tower comprising a side wall extending upwardly and generally perpendicular to said second half shell and a top wall extending generally perpendicular to said side wall and sealing said inspection tower, wherein a portion of said top wall is removed to form an opening to allow access to said at least one component after said first half shell and said second half shell are connected together.

13. A serviceable sealed fuel tank as set forth in claim 12 including a sealing cover to cover and seal said opening.

14. A serviceable sealed fuel tank as set forth in claim 13 wherein said sealing cover comprises a base wall and a side wall extending from said base wall.

15. A serviceable sealed fuel tank as set forth in claim 14 wherein said side wall of said inspection tower has a plurality of external threads and said side wall of said sealing cover includes a plurality of internal threads for threaded engagement with said external threads.

16. A serviceable sealed fuel tank as set forth in claim 14 wherein said side wall of said inspection tower has a smooth outer surface.

17. A serviceable sealed fuel tank as set forth in claim 14 wherein said sealing cover includes a seal disposed adjacent said base wall.

18. A serviceable sealed fuel tank as set forth in claim 13 wherein said side wall of said sealing cover includes a plurality of internal threads being self-tapping to engage said outer surface.

19. A serviceable sealed fuel tank as set forth in claim 18 wherein said base wall includes an opening extending therethrough and a cover plate disposed adjacent said opening.

20. A serviceable sealed fuel tank for a vehicle comprising:

a tank shell having a first half shell and a second half shell connected to said first half shell;

at least one internal component disposed inside said tank shell between said first half shell and said second half shell; and

an inspection tower comprising a side wall extending upwardly and generally perpendicular to said second half shell and a top wall extending generally perpendicular to said side wall and sealing said inspection tower, wherein a portion of said top wall is removed to form an opening to allow access to said at least one component after said first half shell and said second half shell are connected together; and

a sealing cover to cover and seal said opening.
