I got my '59 Apache running this weekend and realized that I installed the wrong fuel pump. There is an extra vaccum line from the fuel pump through the firewall. I also have the normal one that goes from the carb intake through the fire wall.
Now I know that only the windhield wipers use vaccum. I searched through all my manuals and can't find the reference to dual vaccum anywhere. I am sure you guys must know the answer to this and it would be helpful to locate some schematics for how this is setup.
