I am at the point to run some vacuum lines. I have power brakes, A/c, Th350 trans. and Cowl hood. Ground up offers 3 fitting for the port on my manifold behind the carb. ( booster(3/8") , 1 vacuum line or booster 2 vacuum lines and booster and 3 vacuum lines).
I was planning on putting the booster and trans. together.
Where to put cowl vacuum line and A/c vacuum line at the same point or not? If so I will go with the 3/8" x 3 vacuum line correct? Am I missing anything?

Thank you for the help again
Dave

those fittings go on the stock manifolds OK but you got to watch aftermarket manifolds. that fitting with the three ports is nice but it won't go on my eddy rpm. it won't clear the runner in the back, so you can't screw it in. hmardown

Hmar's right, the 3 port fitting won't clear the RPM runner. Go to a hardware store and get a threaded extension to stand off the vacuum fitting, that's what I'm doing on mine.

Get a 3/8" x close nipple and a 3/8" pipe coupling in brass. '69 uses booster and two ports ( trans and vac canister). Would think the booster and 3 port for a 70 with flapper.

sorry forgot about this post. I got Performance Stainless Steel 1042 - Performance Stainless Steel Vacuum Hose Fittings
from summit & then went to speedway parts and got two chrome fittings. one 1/8 npt by 1/4'' vacuum & 1/8 npt by 5/16 vacuum. screw in performance two port fitting & position it so you can screw in side fittings. sweet ! hmardown
