bought this to fix fuel drain back problem

just looked at my old afb.....been collecting dust for years....the one way check valve for the pump is a good 1/2 inch off the bottom of the bowl...plus the volume of gas that the bowl holds once the float is lowered into the bowl seems pretty small...which would make the evaporation problem even worst for these carbs...

plus in my case..the car is in driveway with a slope...with the accelerator pump in the front the gas gravitates away from the pump well...

an electric fuel pump will solve the problem....or as I am going to do for the summer..put my HOLLEY 750 VS carb on it....
