Safety measures for working on the fuel
supply system
WARNING
During assembly work especially within the engine compart‐
ment, due to the lack of space, bear in mind the following:
♦ All hoses (e.g. fuel, hydraulics, activated charcoal filter
system, cooling system and cooling gas, brake fluid, vac‐
uum) and electric cables must be restored to their original
positions.
♦ To provide easy access to all the moving or hot parts.
When removing or installing fuel level sensor or fuel pump, with
fuel tank full or partially full, observe the following:
When removing or installing fuel level sensor or fuel pump, in the
fuel tank full or partially full, observe the following:
WARNING
♦ The fuel and hoses in the fuel system may be very hot
( risk of burns)!
♦ Fuel system is under pressure!
♦ Use protective gloves and eyewear when carrying out any
repairs to the fuel system!
♦ Before starting installation work, place a gas exhaust hose of
a switched on gas exhaust system near the fuel tank opening,
so as to absorb gases released by the fuel. If exhaust equi‐
ment is unavailable use a radial fan ( the motor must be out of
air flow) with air movement rate higher than 15 m
3
/ hour.
♦ Avoid skin contact with fuel! Use fuel resistant gloves!
1.4
Cleanliness rules
For jobs on the fuel / injection system, strictly observe the follow‐
ing “6 cleaning” rules:
♦ Carefully clean all the connections and surrounding areas be‐
fore disconnecting them.
♦ Place all the parts removed on clean surface and cover them.
Do not use cloth that releases lint!
♦ If repair work is not to be carried out immediately, open com‐
ponents must be covered up or carefully preserved.
♦ Install only clean components. Only remove spare parts from
packaging just prior to installation. Do not install components
that have been kept out of packaging (i.e. inside the tool box,
etc.).
♦ With system open: If possible, avoid using compressed air. If
possible, do not move the vehicle.
♦ Also, ensure that no diesel runs onto the cooling system ho‐
ses. Hoses that may come into contact with fuel must be
cleaned immediately. Damaged hoses should be replaced.
