Note
â—† Hose connections are secured with either spring-type or
clamp-type clips.
â—† Always renew crimp-type clips with spring-type clips.
â—† Fuel hoses on engine must be secured with spring-type clips
only. The use of crimp-type or screw-type clips is not permis-
sible.
â—† Spring-type clip pliers -VAS 5024- are recommended for in-
stallation of spring-type clips.

1.1 Safety precautions when working on
fuel supply system
WARNING
When doing any repair work, pay attention to the follow-
ing due to the cramped conditions:
â—† Route all the various lines (e.g. for fuel, hydraulics,
activated charcoal filter system, coolant, refrigerant,
brake fluid and vacuum) and electrical wiring in their
original positions.
â—† Ensure that there is sufficient clearance to all moving
or hot components.
â—† The fuel and the fuel lines in the fuel system can be-
come very hot (danger of scalding)!
â—† The fuel system is also under pressure! Before open-
ing the system, place cloths around the connections.
Then carefully loosen connection to release the pres-
sure!
â—† Wear eye and hand protection when performing any
type of repair work on the fuel system!
Note the following when working on a full or partly filled fuel
tank:
â—† Before beginning work, place an extraction hose close to
sender opening in fuel tank to extract escaping fuel fumes
and switch on exhaust extraction system. If no exhaust gas
extraction system is available, a radial fan with a displace-
ment greater than 15 m
3
/h can be used providing that motor
is not in air flow.
â—† Prevent skin contact with fuel! Wear fuel-resistant gloves!
