Fuel supply system
Fuel is fed to the injector by a pump, a filter and a
pressure regulator integrated with the fuel level in-
dicator inside the tank.
The pump unit is connected to the injector by:
2 semi-flexible pipes
4 quick unions
1 T union with O-ring and retain bracket for the injector
The pipes are crossed and fixed to the intake manifold to prevent wear of the quick unions connected
to the T union for the injector.
N.B.
BEFORE WORKING ON THE FUEL SUPPLY SYSTEM, CAREFULLY CLEAN THE PARTS TO
PREVENT DAMAGING THE FAST-RELEASE COUPLING SEAL OR TO PREVENT DIRT GETTING
INTO THE DUCTS.
CAUTION
THE SYSTEM IS UNDER PRESSURE.
DO NOT SMOKE DURING ANY OPERATION.
PREVENT ANY FUEL SPRAYING.
WARNING
- BEFORE STARTING THE ENGINE, CHECK WHETHER THERE IS FUEL IN THE TANK.
- DO NOT USE THE SCOOTER IN RESERVE FOR A LONG TIME, UP TO THE POSSIBILITY OF
RUNNING OUT OF FUEL.
- IF THE SCOOTER IS EXPECTED TO REMAIN UNUSED FOR A LONG TIME, REFILL THE TANK
AT LEAST TO HALF THE LEVEL.
FAILURE TO OBSERVE THESE RULES CAN DAMAGE THE PUMP.
