Here are the pictures, hopefully they can help others in the future.

Front of the car, shows the bumper and front end removed in order to get to all the fender bolts.

The three ports of the original charcoal canister--the black bits on the floor are the charcoal pellets that came out when shaken.

Last 3 pictures show the installation of the BMW charcoal canister in the left front fender. The fat hose goes to the fuel tank vent line. The skinny plastic tube goes to the purge valve which allows the engine to burn off accumulated vapors.

The bracket of the BMW canister had to be bent slightly to match the contours of the mounting location. I did not have to drill any holes. I did have to come up with some nuts and bolts to mount it. I used some 10mm headed bolts. Be careful pushing the tubes onto the nipples of the BMW canister, they are not all that strong, and mine started to bend a little. It is a good idea to lubricate the hoses before attempting to slide them on.

Also, note the holes next to the canister in the last picture. They are keyhole shaped. This allows you to remove the original canister without having to totally unscrew the mounting screws. The screw heads are on the inside, so you have to access them from above or underneath where there is a small hole, just big enough for a 10mm wrench to loosen the bottom screw. I struggled the most with getting access to loosen them and remove the original canister.

By the way, the original canister sits at more of a horizontal angle than the upright BMW unit.

The BMW canister has an open bottom design with a replaceable filter element. I could not find a suitable element, so I just bought the largest PCV filter element off the shelf at Autozone, and fashioned it into 2 half circles to fit the bottom. There are some prongs on the bottom of the canister that secure the element, and there is also a non-replaceable filter element visible inside the canister screen. I was satisfied with this modification, it is working well.

I have been pulling the cap off the fuel tank to check for negative pressure indicated by air rushing in. There has only been slight positive pressure at times causing a hiss. I know it is air coming out because a few droplets of fuel are pushing out and wetting the filler neck rubber gasket. This is normal according to the shop manual. The vent valve under the tank maintains a slight bit of tank pressure to help deliver fuel to the pump. I confirmed the vent valve was working when I had the tank out by blowing in either direction on the valve. There was a build up of pressure before the valve opened and relieved the pressure.
