Re: What is the best way to prevent Vapor Lock in this heat??
Quote:
The reduction in vapor lock effect seen by compositional changes to fuel (the addition of MMO, kerosene, diesel fuel, or anything else to the gasoline) is basically the result of changes in the interactions of azeotropes within the zeotropic mixture we call gasoline. That zeotrope varies widely by region, brand, grade, and seasonal blend. Deviations from Raoult’s law (vapor pressure of solutions) result from the addition of anything to the complex gasoline mix. Anything that will effect a negative azeotropic relationship with the fuel components having the highest vaporization potential will reduce the vapor lock effect. The opposite is also true, some additives may initiate positive azeotropes. Basically, vapor lock is the start of fractional distillation, and you want to change that paradigm. I'd ask what the hell her answer means, but I know better! So, instead, I asked her what she would do if suddenly stuck on the road with vapor lock. Her answer: That's a dumbass question, pickup my cell and CALL YOU. Suggestion: Try a different brand/ grade, some have way too much butane for cars without pressurized fuel systems. Make sure there are no pressure drop points (restrictions) or vaporization initiators (scratches, rust, dirt) in the fuel system. Oh yeah, and that clothespin on the fuel line thing you asked about? They absorb resonance harmonics that serve as an energy source to initiate vaporization in the fuel line. And mow the grass. I'm not sure mowing the grass would help, but if it was my vapor lock problem, I'd do it anyway. Always remember, the wife is never wrong. Fortunately, I don't have a vapor lock problem, so no need to mow today. |

Re: What is the best way to prevent Vapor Lock in this heat??
I wish i knew how to post a picture. BUT! (and all will laugh) I have no vapor lock issues but I did and experiment. I took a foam beer can cooler and cut a couple of notches and slipped up the sediment bowl. the notches were to clear the fuel lines. I made a simple bail handle to secure the unit to the bowl. On a tour with several other A's I took temperature readings throughout the day with a thermal gun on the metal top of the bowl. Mine was 20 degrees cooler than all the other cars.

only way completely for me is adding a 6 volt fuel pump.

Re: Phillips GAS is BAD!!!!

So....my thoughts are...change gas brand, and insulate the fuel line.. Take both steps first and then remove the insulation with the better gas and see what happens. Thanks MIKE and Thanks to your wife....i think??hahahaha PS when are we going to see you at a meeting.. Are you going to French Lick?
