Fuel tank reservoir

Claim 2

A fuel tank assembly comprising: first and second fuel tank walls being spaced apart a distance; and a reservoir between said walls having a free-state dimension slightly greater than said distance where said reservoir is compressed between said walls, said reservoir defining openings communicating fuel between said fuel tank walls and the interior of said reservoir.

Claim 3

The fuel tank assembly of claim 1, said reservoir further comprising a resilient portion compressible between said first and second walls.

Claim 4

The fuel tank assembly of claim 2, wherein said resilient portion is pleated.

Claim 5

A fuel tank assembly comprising: a first fuel tank wall having a first concave interior surface and a second fuel tank wall having a second concave interior surface spaced apart a distance; and a reservoir compressibly secured between said first and second walls, said reservoir having a first surface matingly engaging said first interior surface and a second surface matingly engaging said second interior surface, said first and second surfaces of said reservoir having a free-state dimension greater than said distance, said reservoir defining opening communicating fuel between said fuel tank walls and the interior of said reservoir.

Claim 6

A fuel tank assembly comprising: a first fuel tank wall having a first concave interior surface and a second fuel tank wall having a second concave interior surface spaced apart a distance; and a reservoir compressibly secured between said first and second walls, said reservoir having a first surface matingly engaging said first interior surface and a second surface matingly engaging said second interior surface, said first and second surfaces of said reservoir having a free-state dimension greater than said distance, said reservoir defining opening communicating fuel between said fuel tank walls and the interior of said reservoir.

Claim 7

The fuel tank assembly of claim 4, said reservoir further comprising a compressed resilient portion which biases said first and second surfaces of said reservoir against said first and second interior surfaces of said fuel tank wall.

Claim 8

The fuel tank assembly of claim 5, wherein said resilient portion is pleated.

Claim 9

The fuel tank assembly of claim 4, wherein said reservoir is made from two or more pieces.

Claim 10

The fuel tank of claim 4, wherein said fuel tank walls are made of metal and said reservoir is made of plastic.

Claim 11

The fuel tank of claim 4, further comprising means aligning said reservoir between said first and second fuel tank walls.

Claim 12

The fuel tank of claim 9, wherein said aligning means are portions on at least said first interior wall surface which engages a corresponding portion on said first wall of said reservoir and orients said reservoir in a predetermined direction.

Claim 13

The fuel tank reservoir of claim 4, said first interior surface of said fuel tank wall defining at least a first aperture and said first surface of said reservoir defining at least a second aperture aligned with said first aperture and receiving a member therethrough.

Claim 14

The fuel tank assembly of claim 11, wherein said member is a fuel pump assembly.

Claim 15

The fuel tank assembly of claim 11, wherein said member is a fuel filler tube.

Claim 18

The method of claim 14, wherein said reservoir is resiliently biased against said first and second walls.
