Dave,
Two years ago I took my 80 Spitfire to Colorado for the VTR (from Kansas
City). At one stop after I reached Colorado I had the same thing happen
and of course my rear window was also zipped out. I thought they had a
problem with the pump, but it seemed to be working ok for everyone
else. So then I thought it was due to either the heat from the long
run across Kansas into Colorado or the change in altitude.
Later I was filling the car at another gas station and noticed that I
was going to have the same problem ( I happened to move the nozzle and
heard a rush of air instead of gasoline). I looked at the nozzle and it
had a shoulder on it that made a tight fit against the ring inside the
filler.
So I decided that what was going on was that it made a seal between the
nozzle and the filler tube, the gasoline going in to the tank compressed
the air up into the area that the later Spits have to let the gasoline
expand (the later Spits extended the filler tube farther into the tank
to create a expansion area due to emission regulations). Then when I
pulled the nozzle out the air expanded enough to shoot gasoline out of
the tank.
I suspect that the ventilation tubes that go up to the carbon canister
should have allowed the air to escape. So I probably have a problem
with a clogged line or fuel separator. But so far I have just been
careful when filling the tank.
