[Healeys] gasoline overflow

[jim brown]

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.

> Once again I overfilled the gas tank and not being used to the NC sun and heat it overflowed with damage to the paint. Second time in 10 years so I was thinkng of adding a T filling to the filler hose and running to a closed catch can in the boot. Has anyone tried this or are there any ideas (other that not being dumb enough to fill up)
