Bosch-Common Rail System – High pressure fuel lines
NOTE: The bending radii are exactly matched to the system and must not be changed.
NOTE: After disconnecting one or more high pressure fuel lines, these must always be replaced. Reason: The reason for this is that leaks can occur when re-tightening, due to distortion of the connections of the old lines. The high-pressure fuel lines connect the high-pressure pump to the fuel rail and the fuel rail to the individual fuel injectors.
