I was just hoping that someone could post the correct set up for vac. lines for a q-jet. Either stock or not. The reason Im asking is because I want to double check the vac. line routing on my car, 800cfm on a TA intake. Kevin
Kevin, I don't have a diagram, but I'll see if I can help. On the front of the carb at the base is a 3/8" nipple that is the connection for your PCV valve. It takes a 2' piece that loops around the carb on the passenger side and goes to the PCV. There are 2 smaller nipples on the upper front of the carb. They are for your vacuum advance. If you want ported vacuum, use the drivers side, if you want full vacuum use the passenger side. There is a nipple coming out the back center of the carb, that goes to the vacuum storage container on the firewall. This runs your climate control doors and heater control valve. Any nipples coming out of the base of the carb vertically are for the front and rear vacuum breaks if used. Power brake vacuum, and modulator vacuum come off of separate fittings on the intake manifold. Hope that helps
