Great news & wld like to know some more details ?
I have a 66 coupe and experienced continuos fuel related issues. It all started after i ran out of petrol one day. what followed ranged from vapor locks, no fuel reaching the carby, and continual stalling. Anyhow I spent unnecessary $$$ getting tank cleaned, carby redone, but the problems persisted. Then I was told the fuel pump was the cause because it was old and therefore was not sucking enough petrol. More $$$, . I replaced the fuel pump and my problem was fixed and i can now see petrol squirting out of both primary jets in the carby.
However, now my new problem is the car runs very rich nothing has changed except for the new fuel pump?? I have also redone the mixtures several times. Another change i have noticed is there is now NO need to pump the accelerator at starting otherwise the car floods.
Question.... Did you experience any similar fuel / carby problems since moving to an electric fuel pump?
Carburetors have A float bowl that always has a reservoir of gas... the engine isn't being fed by a steady stream from the fuel pump like Efi. But rather the pump fills up the reservoir which the carb runs off of.. if this pump magically made your car start better I'd check your float levels.. they may be set too low

My car was sitting for about 3 1/2 years..... the mechanical pump was about seven (7) years old. The rubber diaphragm in the pump was damaged from the ethanol in the fuel while sitting idle, which caused the pump to work inefficiently.How old was your old pump?
Prob would of happened with non ethanol fuel. Anytime they sit and dry out like that it kills stuff like pumps and accelerator diaphrams.

Hi,
What pressure you running at the carb. It's typical, you need a fuel pressure regulator. Most Eddy carbs don't lke more than 5.5 psi. Some Hollys will tolerate as much as 7 psi, depending on the build. They will run fine at 6, for most street rides and even some street strip rides.
