Im trying to install a new fuel filter and its late and im forgetting things now. First off the filter on the left is the old one. The one on the right is the new one i picked up from Hyundai. Now the old one doesnt have the part i labeled x. Also part Y on the new is in a different spot than part z on the old one. I pulled part A off of part D and then pulled out one rubber washers i labeled B. Thats when i looked in the bottom of the bucket and found part C. No idea where it came from. Thats my big problem. I then pulled the other rubber washer B out of Part D and thats where i stopped. Im hoping part C just came out when i pulled out the first part B, but i have no idea.
