Now that I’ll have a chance to drive my ’62 Cutlass after some tidy up & detail work, I filled the gas tank, and the filler neck overflowed pretty quickly. Once it settled at a level just under the cap, I figured it would be O.K. once I burned some off the next day. When I returned to the garage later, there was a large puddle of gas, which had escaped from the neck. Removing the cap, I could see bubbling gas that continued to spill over. Finally, I decided to siphon the gas down so there would be none in the neck, and it seems to be fine now. Is there some secret on how to fill these tanks? Thanks, Mike
