Okay, first off-I have driven my car with a partial tank of gas with it hotter than today. (Electric fuel pump--fairly new. . single carb)
Today at about 5:15 pm, I filled the tank, drove 10 miles and stopped to get the mail. Re started the car and drove 10 feet. . it died. Managed to get it to off and on to sort of run the 150 yards to get it home. We also have ALOT of wildfire smoke in the air. Thoughts and suggestions? |

Relocate it to the front trunk or under the tank. This will solve the problem. This is what the factory did.
Another option is a fuel regulator with a bypass to the return line. This will flush cool fuel through the lines and back to the tank. Thus filling the bowls. Fuel pumps start to cavitate with air (vapor) in the lines. When it cavitates, it will not pull enough vacuum to draw the fuel from the tank. The only way to get the vapor out of the sealed system is through the carbs. This takes time, most people just wait for it to cool down. The fuel will re-condense and turn into liquid. |
