A filter would let the vapor pass to some extent but the carburetor couldn't mix vapor and air. Remember the needle and seat... The float would fall down pulling the needle from the seat until enough liquid fuel filled the float bowl raising the float again. In among the carburetor "stuff" it had to be able to draw fuel to mix with air in order for the engine to have the right mixture and so on... You would think someone by now would have figured out a way to use that heat and vapor to keep an engine running. After all you only need to light the fumes to ignite gas. Hope no one runs out to prove or disprove that theory... ----- Original Message ----- From: clifford To: [email protected] Sent: Thursday, February 21, 2008 8:07 PM Subject: [BlindHandyMan] vapor locked engines
Dear List members: Back in the twentieth century, when I took physics, the reason given for vapor locking was that the fuel pump would only pump a liquid, and if the engine got too hot, and at that time the fuel pump was attached to the engine, the liquid fuel would become a vapor when super heated and the pump would stop working. The answer to immediate relief was to cool the fuel pump with water or let it rest. I am not sure, but I would think that a filter would let a vapor pass as easily as a liquid? Placing an electric fuel pump in the fuel tank, has eliminated vapor lock, at least the old fashioned type.
