Jason, I am wondering if you are using a 1/2"(inside diameter)hose to supply the booster. I also noticed you made mention of splittiing the vacumn hose via "T"or"Y"--- I would suggest making the vac. hose to the booster a separate hose that comes from the manifold(large 3/8/npt threaded boss) and run your other vac.lines off the carb.Also do not use "fuel line" hose for this as it is prone to collapse when used as a vac. hose. Large vac hose is available and it may be sold as PCV hose in your area. It has a much thicker wall. Paul
