123 Diesel Fuel Trunk Smell Fix Kit

Fits all 123 sedans, coupes, and wagons 1977 to 1985. These are the parts you need for the cure to a very common problem. There is nothing worse than fuel smell coming from the trunk of your 123. Gasoline is downright dangerous and diesel is quite obnoxious. The single biggest reason for this smell comes from a combination of two things. The old fuel cap seal starts leaking and the deteriorated fuel tank neck seal fails to keep the fuel from running down the tank neck into the trunk.

The way to fix this is to install a new neck to body seal and a brand new factory Mercedes fuel cap (do not buy cheap imitations or you will not fix the problem). Along with these items we are adding a specail upgraded gas cap seal that is touted to last longer than the original seal. This is an easy to install kit (no instructions needed) and you will love the results.

If you are running biodiesel the fuel will tend the swell the rubber seals. This kit will keep the biodiesel out of your trunk.
