I hooked up a fuel pump to the bypass cover
One side of the pump will go to the tank
The other side of the pump will go to the carb
Per Franks statement
I will block the nipple with the red arrow with a vacuum cap or take out nipple and put a screw in or solder it closed
The nipple with the yellow arrow will go to the vacuum switch
I believe that is correct.
What I needed to know was which nipple was for the vacuum switch
