ok, so twice last week, now that we are above 95 degrees with 150% humidity, I have had vapor lock issues. I'm talking about my 54 Bel Air, 235 - power glide. Bone stock. The first time I let the car cool for a few hours and then it started right back up. The second time, I was able to pour enough cool water over the fuel lines to get the fuel to condense and re-prime the pump. So off to Home depot I went and bought some of that high density HVAC copper line insulation stuff. It looked like hell under the hood, but since this is my daily driver, I did not care. Function is more important than looking good. This seemed to fix the problem for a few days. So today I went to lunch and sat inside for nearly 45 minutes, came out, and sure enough, vapor locked. Yanked the insulation off, and cooled the lines off with water again, got me back on the road. Then tonight while I sat in line for 10-12 minutes waiting on some chinese food, it vapor locked while idling in the parking lot. I am a little bit pissed off at this point. Here in Oklahoma we have been blessed with 10% ethanol, as most of the rest of you have. I would assume that ethanol has a lower vapor point than gasoline? So that is probably part of my issue. So besides spending more money, and being inconvenienced with locations that sell straight gasoline, what options do I have? I know that lengths of rubber fuel line can make the problem worse. But in my case, everything under the hood is stock, and the fuel line is hard lined from the tank, through the pump, all the way to the carb. Anyone have any creative suggestions? I'm not crazy about having to pour a gallon of water on the fuel lines every time I want to go somewhere.
