Check Integrity of Fuel Supply Lines

Model: Mercedes Classe E W210 - Years 1995-2002
Part: Engine

During routine maintenance, it is advisable, and strongly recommended, to check the integrity of the fuel supply lines. This is an aspect that is generally overlooked and addressed only when failures occur. In reality, these lines can become damaged due to the chemical action of gasoline, pressure, temperature, and mechanical stress from vibrations, especially at bends and junctions. A rupture can cause not only a loss of pressure in the system but also a fuel leak with obvious consequences. Therefore, if any line appears deteriorated during maintenance, it is suggested to replace it proactively.
