FUEL SYSTEM
DANGER !
Stop the engine and let it cool down before refuelling or
carrying out any operation on the fuel system.
CAUTION !
Fuel is flammable and can be dangerous. Fuel spilled on
hot surfaces or near sparks can ignite. Do not step onto
the injection pipings. Take care to always keep them in
good condition.
WARNING !
Total cleanliness must be guaranteed when working on
the fuel system. No impurities should enter the injection
system. Make sure not to spill fuel on nearby hoses.
NOTE !
Any work on the fuel injection system must be carried
out by a authorized Nanni technician.
Check regularly the condition of the components of the
fuel system (hoses, filter, clamps, etc). When a clamp
is removed, replace it by a new one, always in stainless
steel.
WARNING !
The fuel feed pump is an extremely precise unit. Water
entry in the fuel system will cause major failure to the
injection pump and to the whole fuel system.
