"Vacuum" cannister?
Quick question.....the cannister located underneath the brake booster on the driver's side, is that thing supposed to hold a vacuum?

vacuum canister?
no, i think what your refering to is the vapor canister for the fuel system. in a perfect world when the car was new it was designed to contain vapor from the fuel tank and burn it through the engine to reduce raw fuel emissions.

Canister
Is the charcoal canister needed?? The hose that goes from the canister to the engine was cut and left open near the top of the fender when I bought my car. Since I didn't know where it went it has always been like that.

It is a place for fuel vapors to accumulate from the gas tank when the car is parked, they are then drawn into the intake manifold at startup. It's an emission device designed to keep unburned hydrocarbons from being released into the atmosphere.

Under certain conditions that canister can have fuel come up the lines, check the hoses to it. There b itch to see and to check but we almost had a fire as a result of cracks in the factory rubber lines that were never checked or replaced.
