Re: Fuel pump turbulence 8BA
I know you all think I’m nuts and not very credible… sorry you feel that way…
My experience is from years of driving Model A’s on tours around the country. Remember they are a gravity fed system. When ambient temperature is 70’s to upper 80’s all is well, no problem. But when ambient gets above 90, things change. Ethanol will boil in the fuel bowl. Looks like a little water spout inside the bowl. Along with comes vaporization in the top of the bowl. Typically happens when slowing down from cruising speed to traffic conditions.
Same car and same weather conditions, Non-Ethanol, no boiling, turbulence or vaporization.
It also occurs with my other drivers, 36 Ford, 47 Mercury and 54 Chevrolet.
The only successful remedy we have found is cooling the fuel bowl.
If Non-Ethanol is available to you, give it your own test…
I’m sure most of you can remember when gasoline was not ethanol … this problem didn’t exist.
