reduce fire risk.
Installation, fuel pipes
1. Always use new copper sealing rings during
fitting.
2. Tighten union nuts and banjo bolts to the
specified torque. See "Technical data".
Note:
In the event of a leakage from a pipe coupling, do
not overtighten the union nut. First check whether
the leak is at the connection point between the
pipe and coupling or at the connection point
between coupling and the component housing.
If the leakage has not stopped after the union nut

has been tightened, it will be necessary to take
the coupling apart.
Check the parts for deposits and/or damage.
Pipes may chafe if they touch each other or other
parts of the vehicle.
Pipes showing evidence of wear must be
replaced without delay.
