Getting Rid of the Gas Smell

After the slightly colder weather forced me to roll up my windows for the first time since the car has moved on it's own, I realized that the smell of gas from the trunk was nearly coma-inducing. I temporarily fixed the issue by sealing up the speaker holes in the rear deck. To attack the actually problem, I inspected the vent tube in the trunk. As with all early 02s, the tube just runs from the filler neck to a little hole at the rear of the trunk to vent outside. As with many early 02s, the little grommet that holds the tube in place and prevents fumes from re-entering the trunk has disappeared. Not satisfied with merely fabricating a new grommet to replace the NLA one, I mimicked the later 2002 models' carbon-fume-capture system.

First I bought a bottle of fish tank filter activated charcoal, some 3/8" - 1/4" tubing, a few 1/4" brass fittings, some JB Kwik, two brackets, two 3"-5" plumbing hose clamps and a quart-sized paint can.

Next, I drilled a hole in the lid and the can.

I then glued the fittings in from the inside and filled the can with the charcoal pellets.

I snapped the lid onthe can with the above orientation.

While I was waiting on the glue to dry, I pop-riveted the brackets together. I later expanded the 90 degrees bracket to be a little more obtuse.

I bolted the bracket to the existing hardware in the trunk.

Next, I cut the vent tube off just a few inches from the filler neck.

I then ran the tubing as seen above. The bottom tube runs to the original exit hole, but sticks out a bit further.
