Went from 2 barrel to 4 barrel Qjet and need a vac diagram

I went from a 2 bbl to a 4 bbl mercruiser q jet carb and a new intake manifold. Finally got the carb and im curious if anyone has a vacuum diagram for the carb. Thanks!

Boats do use a vacuum advance. You may not have a marine carb. There is a line from the fuel pump to the carb that is clear if that is what you are talking about that is for safety in case the diaphragm ruptures.

thinking the vac dash pot to pull the choke plate open, most good auto stores will have it.

This was it. Carb didnt have the hose and I found one at the auto parts store. Thanks!
