The small hose you refer to comes out of the filler neck tube, goes forward
behind the metal work, across the car and down to a small metal tube on the
top front of the left side tank. This is the means by which the left tank
gets air as its fuel goes down, and conversely how air escapes as the tank
is filled. Although you only fill one side, the two tanks are joined by a
fairly large (maybe 1.5") pipe which goes from the back bottom of each tank
across the back of the car. The pipe is made up of a large centre section
and two curved end sections, joined to each other and to the two tanks by
short rubber sections.The larger centre section has a small take-off,
pointing down and through the floor metal, to which is joined the fuel line
under the car which then goes forward to the fuel pump.
The small hose you mentioned, the fuel neck rubber, and the four sections
of rubber in the pipe across the back of the car, are all prone to
deterioration, particularly if they are original, and a crack in any one of
them could be your problem.
Once you remove the two trunk side panels, and the smaller panels across
the back of the trunk (tedious but no great problem) you get access to all
the bits except the small hose at the front, but you can at least see both
ends of it.
Hope this helps.
