4.7 REMOVAL AND INSTALLATION, FUEL PIPES

Removal, fuel pipes
1.

Disconnect the earth lead from the battery

terminal.

2.

Disconnect the appropriate fuel pipe and

collect the escaping fuel.

3.

If the pipe is damaged in any way, it should

be replaced.

}

Leaks from fuel pipes must be

remedied as soon as possible to

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.
