It should only flow with vacuum applied.
There are two spigots that look like they are for the vacuum hose but only one is real.
The spigot that points straight down is a tell tale to let you know if the diaphragm is leaking, while the one that is horizontal is the actual vacuum port.
Make sure you got that right and while the engine cranks pinch the vacuum hose off, this will allow you to stop cranking and still fill the float bowls without killing the battery.
Good luck,
