Mercedes Vito: small fuel leak - fix
EN
That item is dedicated to one really tiny problem, that actually cost lot of troubles. The car is van Vito from Mercedes.
the fuel was sprayed somewhere between the intake manifold. And the problem was: loose 6mm hose, and broken return hose.
- first need to remove the top half of the manifold.For that you need M10 socket to get all 8 top manifold bolts. Then, from behind (left near the EGR vacuum membrane) there is one bolt, and the two nuts keeping the EGR pipe halves together(right back, if that is actually EGR)
- then air intake pipe, and map pipe.
Once removed the top cover you have kind of access to the rail and that particular point with the two hoses attached. Only took out the return one(round in red) and cut small piece from the beginning, and the same from the small one(marked in blue).
Little heat the pipe to get it soft for easy assembly on spot and voila! Job done. Then fit all back and try to warm the engine little and see if there is any leak. Hope it helped
