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.
