Fuel pump turbulence 8BA

[FlatTopFreddie]

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.

Freddie, you’re not nuts and many if not most of us have experienced similar problems. But then there are those who haven’t had any of those things happen to them and blame it all on poor maintenance. It’s curious that those are the same folks whose grandmothers believed in keeping a ladleful of water handy at the well pump in case she had to prime the pump to get water in the morning.

Finally got my rebuild kit installed on the pump. My old sediment bowl gasket was rubber and cracked, but stuck pretty good the the housing.
My kit came with the cork one.

The original rubber flex line from the pump was not present, so I installed one.

Question.......is the female end 7/16x24? It appears to be an inverted flare, so I am planning on 1/4 brake line over and down to my filter and main line back to the tank. Main line is 1/4 inch copper.
