I have a Demon 650dp on a RPM air gap manifold and the problem i am having is what to do about the vacuum for the booster because the bowls on the carb hang over the vacuum port on the manifold. What should i do because i need to run vacuum for my booster and PCV but only have one big vacuum port on the carb. thanks.

 

You could use a T fitting to connect both to the port on the carb.

 

Edelbrock makes a 90 deg low profile fitting to solve this exact problem. Part #8096
