My vacuum canister, and the one off the 1972 V8 car I have some parts from, are both cylindrical 'coffee can' shapes. They are definitely not a softball shaped sphere. Both these cars are factory AC though.
My 74 mav has a coffee can shaped vacume canister as well. It's a/c car also and it was mounted just below and behind the charcoal canister.
Well, the canister does have a ridged line that connected to the stock air filter, and I can't see why a vaccum canister would do that, for my car I'm gonna go with Corbin's answer. That line has been unhooked since last winter too, and hasn't adversely affected my miledge so...
I wasn't trying to prove anyonw wrong, but I have factory air in my 73 302, and it was in a softball shape. I don't doubt that you guys has cylindrical ones, I just wanted to answer '72 Comet GT's question correctly. Sorry if I angered anyone. -Corbin
No Anger here I don't think anyone can claim to be an expert on these minor details, that's why I just posted what I've seen.
Do not plug the line unless you vent your gas cap. My factory gas cap didn't vent well enough and I vacuum locked. I just leave it unplugged.
If you still have the carbon canister, I would suggest hooking it back up to the air cleaner. I just took the nipple from a stock air cleaner, bored a hole in the base plate of my new air cleaner, dropped the nipple through, and hooked up the hose. The cardboard tubing is still available from Ford. Part # D4ZZ9D667A for a 40" piece. Its better than letting fuel vapors collect under your hood and dosent rob any power.
naw no anger just wanted to make sure what he was talkin bout. and yes it will be the charcoal can if it has a tube running to the air cleaner
Cool, glad that's cleared up. I wonder what the deal is with the different stlyes of vacuum resevoirs? I can't see a distinct difference in all our Mavericks/Comets, that would make them have different ones. Maybe it's like the fuel line differences... -Corbin
mavaholic, please don't post any more pictures of your engine on the net, it's too hard to clean the drool off of my keyboard. nice looking.
