MBE 900 Series Engines - HP Fuel Line Recall
I thought that a recent issue with my 2007 Gulf Stream Tour Master, which was built on a Freightliner Chassis and is powered by a Mercedes MBE 920 engine, might be of help to other owners with similar combinations.
Our coach had about 12,000 miles when we noticed the smell of diesel fuel when we stopped for the evening. The engine was leaking a small amount of fuel and I traced it to one of the high-pressure fuel lines located on the top of the engine going from the block into the injectors.
While working to get this corrected I became aware of a recent recall on the Mercedes engines (NHTSA 08V668000 and 09V141000). I called Detroit Diesel -- they handle the Mercedes engines -- and was told that my engine serial number was not in the recall. Further investigations with various dealers revealed that a Mercedes recall (08C3) provides for a complete replacement of all un-dampened high-pressure fuel lines and fittings. My engine did not have the new dampened HP lines.
I followed the service issue procedures in my Mercedes engine owner’s manual and finally contacted a regional manager. He was very helpful and agreed to complete the recall (08C3) without charge. Needless to say, I was relieved to not have to pay for the four hours of labor and needed parts.
My main reason for communicating with Tech Talk is to make other owners with this engine aware of a potentially serious situation that could occur as the result of a fuel leak. Friends of ours in Texas are the owners of a Alfa See Ya motor coach with the same chassis and engine combination as mine. They had a major fuel leak that left them shaken and stranded on the side of a highway and just glad that the leak did not develop into a serious fire. Neither I nor our friends were contacted by Gulf Stream, Freightliner or Detroit Diesel concerning this recall. I’m sure there are others who may be in the same situation.
