SAFETY MEASURES TO REPAIR THE SUPPLY SYSTEM
1. Before carrying out any intervention on the supply system, disconnect the battery negative (-) cable.
2. Do not smoke during the interventions on the supply system. Besides, do not carry out any operation
with open fire.
3. Also with the engine off, the supply duct (between the fuel pump and the fuel delivery pipe) is still
under pressure. Before loosening or removing the pipes, release the fuel pressure according to the
"procedure to release fuel pressure". Also after releasing pressure, a small fuel leak can be detected
when pipes are removed. Therefore, before removal, it is recommended to cover with a cloth the part
to be removed to avoid fuel spraying.
4. The connection method of fuel pipes or vapour emission pipes is different depending on the pipe
type. When fuel pipes or vapour emission pipes are refitted, carry out the connections adequately and
lock the pipes referring to the figure on the side. Check there is no twisting or signs of wear after carrying
out the connection.
