A wrench told me my gas can boil if the fueline is touching the heads or block...causing the carb to act up/ This true?
Thanks,

Do you have a rubber fuel line....if so no way!

 

I wonder if thats why mine acted up this weekend in near 90s temp w/pretty high humidity? The bike would stumble/hesitate coming off in first gear only(like after sitting at a light).

 

If the fuel was really boiling....then the hose or tube would probably be in the process of melting. More possibly, it would be on fire!

 

Fuel boiling does in fact happen. The term "Vapor Lock" describes the phenomenon, and it typically happens during very hot weather with gasoline engines, or at very high altitudes with normally aspirated aircraft engines.High altitudes lower the boilingpoint of fuel in any gasoline engine, which can cause vapor lock even under conditions that wouldn't allow it at sea level.Fuel Injected engines tend not to suffer vaporlock since the higher fuel system pressure raises the threshhold at which the air begins to separate from the liquids... Hence, the phenomenon isn't seen much these days with the newer fuel delivery technology.

So yes, you could have fuel boiling in a gas line. However, if you suffered vapor lock, you'd likelyknow it straight awaysince the enginewouldn't be running too well, if at all.

 

I agree with you ZD....we used to install a coffee can with a coiled up fuel line in it with dry ice in our race car in the sixtys to stop the vapor lock. But like you said today this is not a problem here on the ground and 99.9% chance it's not his problem and thats why I said no way.
