Hi, I'm running an Edelbrock RPM intake which only has (1) 3/8 npt vac port. I need 1 for the lights and 1 for the PB. The PB hose is twice the size of the light hose. I didn't get to NAPA to see what fittings they have in stock. What fitting(s) did you run for both? I'm thinking of running a large ID fitting and "T"ing off that for the lights.
Thanks,
Gary

My power brakes attach to a 9/16" fitting in the base of my Q-Jet. The headlights/accessories vacuum line connects to a 1-way OR 2-way NPT fitting in one of the rear intake runners. I don't think the two should share the same vacuum connection.

Ok, the original Q-jet also had the rear vac tap for the PB but the Q-jet I'm running doesn't have that provision. The Q-jet I'm running is from a 69. The only vac tap I have is in the runner. There must be several guys out there who have a setup like this?Maybe a picture is worth a 1000 words..or something like that :crazy:
Thanks,

Check the vac fittings section in ZIP seems they have fittings for the intake port that have the correct number of fittings. I think as long as you have the 1 into 2 connection that is 1 way for the lights and interior acc you should be fine.

This might be what you are looking for:

Thanks Chris that looks to be what I'm looking for. Do you see any problem running the PB and ligths off the same runner for supply?

I am not certain if the pb booster has a build in check valve or not but I would think as long as you had a check valve in line you should be fine. If you think about it all the vac acc are getting vac from the same source whether or not they are hooked up to the same port.

I'm going to check with NAPA to see what dual port fittings they have,if not I'll order one.
