Ok time for my thesis on why. Now I learned my thermodynamics from my Professors. Professor Ludwick Von Drake and Doctor Vinnie VoomBots. I know, I know, you guys are already saying this ought to be good and it will be. Now where was I? Oh Yes! When crude oil is taken out of the ground it doesn't see the light of day (the Sun) and it is heated and separated by heat into it's component liquids (gas, oil, plastic, nylon what have you), Then cooled and sent to it's proper tanks for other additives to be introduced to screw it up into winter and summer blends. After this it doesn't see heat again until used. It is then transported to the white holing tanks for distribution. The white reflects the sun to keep it cool. (Can you see where I'm going with this?) After this it is put into truck tanks that are silver and transported to the gas stations. You may not be aware of why the tanks are silver but it is my belief that wind rushing of silver tanks at 60-70 mph keeps the temps of the gas stable at 62.6 degrees through the process of aluminum foil on a bologna sandwich in a lunch box. (That is why the bread is soggy when you unwrap it) When the trucks reach the gas station the the contents are pumped into under ground tanks that store gas and keep the temp around 65 degrees. Now when we pump the gas into our cars of different colors we lose the thermal properties of silver and under ground tanks. Which now brings us to the eggheads and nerds screaming about global warming, climate change or what have you. The fuel in the cars now have a new playground to expand and contract with no rules at all. In the case where the outside air temp fluctuates thru-out the day it leads to vapor lock and flooding at the same time. The engine heats up and the fuel expands next to the heat source and leads to vapor lock when the car is slow or stopped due to no airflow thru the engine compartment. The fuel in the carb boils and settles into the intake which is kept cool by the air being sucked in and by the vacuum effect is cooled down. This results in the 5minute stop being subjected to flooding because the exhaust manifolds can't heat the intake manifold to evaporate the fuel. Conversely in hot areas like the southwest, the air is always hot and does not cool down as much as in the above described process so the fuel in the intake evaporate in 2.7 minutes so no flooding. This does however leave the issue of vapor lock. It is my belief that the warmer fuel in the southwest is less prone to vapor lock because it has evolved to enjoy the warmer weather. This is why so many people flock the Florida and Texas from New England in the colder times. Also since most of the Mopar owners above the Mason Dixon line only drive there cars in the nicer weather the gas is going from cold to hot to cold and so on, this leads to more case of flooding and vapor lock. So in conclusion to my thermal thesis I think I have demonstrated that: 1. fuel likes to be in a atomized or gaseous state so that it can enjoy the warmth it has been deprived of and 2. Either move down south to enjoy your Mopar or only drive it in the cooler or cold months where your heater doesn't work or is not installed so the fuel doesn't know what it's brethren in the south has discovered. 3. The climate of the 40's and 50's wasn't subjected to the thoughts and ideas of the so called experts we have now a days so it stayed stable and not effected by the whims of the internet, thus the cars and fuel back in that time had no idea that things could be otherwise and did what they were supposed to do. And for goodness sake don't drive your Mopar from south to north so the fuel can let the secret out. Now that concludes my thesis and I will humbly accept any discussion and feedback on the matter.

Most likely the problem is not lack of fuel but too much fuel. The hot carb boils fuel and it overflows and puddles in the intake manifold. When we try to restart the engine the puddle creates a mixture that is too rich to run until the engine turns over enough times to pull the over-rich mixture out of the manifold and cylinders. Once that happens, the mixture returns to normal and the engine starts. I run a full-time electric pump and still have this heat-soak issue in my car so the electric pump isn't the solution. Some have suggested adjusting the carb float to lower fuel level in the carb to inhibit boil over and flooding the intake manifold. Using non-contaminated gas might also help but I've always used cheap 87 ethanol. This is a well-known problem, best remedy is probably a healthy battery that can spin the engine until the flooding is cleared.

I think a carb spacer between the intake and carb, a fiberglass type heat shield wrap around the steel fuel line, routing the fuel line farther away from the hot manifolds, are all options that should help vapor lock or boiling fuel.
