Just bought a set of blower carbs for my boat. Where is the best place to pick up vacuum off of my intake? Do you guys ahve to tap into the manifold? Should I run seperate fittings for each carb or can I tee off of the same fitting in the manifold and run each line to it?

you have to get a vucume source below the blower, I had to drill and tap my wieand intake..Rob

I run a tee off the same fitting on my weiand intake. Works great!
