Actually, the only intense part was figuring out what was inside before I opened it, and how it was supposed to work. (An early 70s Chrysler book will be much better than the mid 80s AMC manual.) Don't let all the explanation make it look difficult. Taking it apart and putting it back together was pretty easy. Cutting the plastic weld or glue line is the only real 'trick'. Hey the other guy just hacksawed his and taped it together. The filter material and charcoal are all that yu need to buy. I didn't even buy new charcoal ('cause I forgot).
But as there's no indication that anything is wrong with yours other than a dirty filter, I wouldn't take it apart either.
