Non Return Fuel Rail System
NON RETURN FUEL RAIL SYSTEM
The S62 engine utilizes the same method of meeting Running Loss Compliance as previously seen on the M62 TU. The regulated fuel supply is controlled by the fuel pressure regulator integrated in the fuel filter assembly (pressure testing tap at this point). A fuel return line is located on the filter/regulator assembly. The system provides even fuel distribution to all fuel injectors due to a "T" connection feeding both fuel rails. The new fuel rails do not contain a return line.
