Mike,

I had a Triumph Herald that acted like you describe.

It would occasionally suck air thru a pinhole in the fuel line between the
tank and the pump.   It was a metal fuel line that was rusted just enough
for a pinhole to form.  The pinhole was at a point in the line that was
above the fuel tank, so it did not leak fuel.   The  pump was mechanical
and would not re-prime itself.  I would  blow into the fuel filler until I
pushed enough fuel to the front of the car to prime the pump and restart
the engine.......  I was 16 years old and knew nothing about British
cars......  (Still don't).

I had another British car that would occasionally act the same way.  It
turned out,  the vented fuel cap had been blocked with rust and the car
would stop running after a short drive if the tank was near full.  It took
me a while to find the problem, but the best hint was, the more fuel that
was in the tank the shorter the distance the car would travel before
stopping.  The more air that was in the tank, the longer it took for the
fuel to stop flowing.

How often does it act like this?   I seem to remember you having a problem
like this a short time ago????
