1. WARNINGS:
Place the vehicle in a quarantined area and arrange "No
Smoking/Petrol Fumes" signs about the vehicle.
Before any work is carried out on the fuel system, ground the
vehicle to earth and maintain the ground connection until the work is
complete.
Do not smoke or carry lighted tobacco or open flame of any type
when working on or near any fuel related components. Highly flammable
vapors are always present and may ignite. Failure to follow these
instructions may result in personal injury.
The fuel system remains pressurized for a long time after the
ignition is switched off. The fuel pressure must be relieved before
attempting any repairs. Failure to follow these instructions may result in
personal injury.
After carrying out repairs, the fuel system must be checked visually
for leaks. Failure to follow these instructions may result in personal
injury.
This procedure involves fuel handling. Be prepared for fuel spillage
at all times and always observe fuel handling precautions. Failure to
follow these instructions may result in personal injury.
If taken internally do not induce vomiting, seek immediate medical
attention. Failure to follow these instructions may result in personal
injury.
If fuel contacts the eyes, flush the eyes with cold water or
eyewash solution and seek medical attention.
Wash hands thoroughly after handling, as prolonged contact may
cause irritation. Should irritation develop, seek medical attention.
Relieve the fuel system pressure. For additional information, refer to the

the flow and pressure supplied by controlling the operation of the fuel pump using a PWM (pulse width modulation) output. A
LP sensor is located in the fuel feed supply line to the engine and is monitored by the ECM for fuel pump control.
Two fuel level sensors are installed in either side of the saddle tank. The sensors are a MAPPS (magnetic passive position
sensor) which provide a variable resistance to ground for the output from the fuel gage.
The fuel system also incorporates an EVAP (evaporative emission) system which is part of the on-board refueling and vapor
recovery feature. The function and operation of the system is designed to meet EVAP requirements to minimize fuel vapor losses.
