Thanks to for all the ideas on fuel expansion and overflow. I'll see how things
look after the paint shop finishes trying to wet sand out the crazing and touch
up the rain channel in the boot. Looks like a new cap and an overflow would be
the way to go-other than the obvious not overfilling. Actually I only filled it
until the gas bubbled up the filler neck and then settled back down into the
tank so I was surprised that it expanded to that extent(it was in the 90's and
the car was in the sun). As usual the list has been very helpful.

I had the same problem when I had acrylic lacquer on the car. I installed an
overflow tube. With its current base-coat/clear-coat, I have not had a damaged
paint problem.
I drilled and tapped the filler pipe a few inches down and installed a right
angle fitting. I then ran a length of copper tubing down and through a drilled
hole with a grommet installed. The pipe exits inside of the rear spring and
forward of the rear outrigger.
I probably shouldn't but I do fill my tank up to the point that I can see the
gas in the filler. I do this generally when I want to check gas mileage. I do
NOT fill up when I get home if I am not going to drive the Healey for a while.
If I do, invariably it will expand and overflow on the driveway. Then
you-know-who gets on my case. You sure don't want that to happen in the garage
next to the water heater.
It doesn't happen often but I have had nozzles fail to shut off when they
should and cause an overflow. For that reason, I never set them on
'automatic'. When I get to the point that I think the tank is almost full, I
pull back the nozzle and hold back the rubber cover (California evaporation
recovery system) so that the pump will continue to work and I can hear and see
the fuel coming up the neck. In most cases, when the automatic nozzle pops
off, I can still add a gallon or more to the tank.
