Vaccum line confusion

[macascio]

I need to know this: on the charcoal cannister there are 3 spouts, what hooks to the spouts or better yet where are the hoses coming from? on the brake booster where is the best vaccum from? does the carb, vent to the air cleaner, if not, does the aircleaner have 2 vaccum lines? this is too confusion. I have had vaccum so strong that my rear fuel tank almost collasped had to unhook the line from cannister just to get fuel cap off. is it also ok to tie both fuel tank vaccum lines into a t then fun the one line to the cannister and if so to which spout on cannister? tia mark

one large one is just a vent with a mushroom shaped cap,one large one goes to air cleaner,a small one goes to perge on carb(if needed)and to vapor cannister behind drivers seat behind door post .no vacume lines are hooked to it.
