Leak from fuel pump/filter area
Hello All,
If you look at the bottom of your C43 (maybe C36 also) facing the rear on the passenger side, do you see any signs of leaks from the fuel pump/filter area? I didn't notice this until I looked under the car, but I saw signs of leakage from the gasoline supply system (pump, filter, tank), but I'm not sure where it's coming from. You'll not be able to see drips on the floor because of the pan cover. The leak seems severe enough that it ran over toward the exhaust pipe.
Do you guys also see fluid leaks on the rear transaxle?

no leak on mines, however, if you are leaking that much, it is advisable to jack up your car and take off that plastic cover to see where it is leaking from. it could be something as simple as the hose clamps or banjo fittings.
first try to see where it is leaking, then tighten all clamps and fittings, also check the hose for any cracks.

c43 gas leak
My c43 is leaking from this area too. Not bad enough that it leaks on the ground, but enough that I can smell it when I'm underneath. I havent taken the plastic guard off yet but it looks like it is coming from the rubber fitting on the Fuel Pump. The fuel pump is the one closer to the front of the car right? Not sure if I can tighten something or if i need a new one...

My 43 is bone dry in that area, but my second MB (C240T) had a small gasket leak at the exit of the tank which made that right rear corner smelly with gasoline when you passed by. My tech did the repair and said it was simple.
Small seepage is normal with our old cars as the rubber and gaskets dry with age... You just need to check and be careful if you smell gasoline. You don't want your pride going up in a big fire
