Vacuum Line Questions

[BabyBlue]

Just need some help with a good placement of the vacuum fitting, and what lines go where. I have a line from the Tranny that I know is a vacuum line and the dizzy, and the carb I believe, but where do they all go? I'm not even sure the tranny one was hooked up with my sbc in the blazer.

vacum from tranny goes off manifold back by your dizzy off that small 90 fitting.it should have been hooked up or it wouldn't shift.the one from dizzy vacum pot goes to lower left port on your edelbrock.big one on back of carb to pcv in valve cover.then you need manifold to brake booster line.i'm not familar with what your setup is for the other port on your t fitting is.

From your description so far... I should place the fitting probably in the right side like in the picture and the tranny line and brake booster line will go to that. Then I have the pcv valve go to the front of my edelbrock carb and dizzy canister line to the lower left port on the front of my carb...is that right? And you have no clue what the 3rd port or my fitting is for? Thanks boat, this is really helping my out...I might actually finish the thing if I can get my radiator mounted right.

thats like mine..........better said.than i could explain.only i have hydroboost brakes no vacum.you should have a bigger line from your brake booster than your other's.you'll need a 1/2 dia. 90 off back off manifold dedicated for that it's not the third hookup on your little t.i think it's 1/2 inch they'll know at auto parts store.
