As is the case with any rubber parts on your approximately 30 year old car the fuel filler neck seal on your W123 may not be functioning as it should be. If you use alternative fuels this can be exacerbated by the fuel's reaction when it contacts the rubber. Change it today before you get water, fuel, or dirt in to your trunk through this opening.

    • Here's one last look at the damage done by the biodiesel. The owner of this W123 will be more careful in the future not to drip fuel on the filler neck seal when filling with B99; at that concentration, biodiesel is very caustic to rubber. Lesson learned!
