FUEL PUMP MODULE
Assembled on the fuel tank bottom left side
The fuel pump creates a positive pressure in the fuel lines and pumps gasoline through the
injector. The Pump operation is determined by the ECU so that it gives exactly the required
volume of fuel. The Pump maintains a uniform (294kPa) fuel pressure. Any excess pres-
sure is bypased back into the fuel tank so that the fuel hose, injector etc.do not get
damaged due to excess pressure.
The fuel pump module has an inbuilt micro fuel filter which filters even the most minute
dust particles to prevent damage to the seat in the injector.
The pump is located inside the fuel tank so that it is submerged in liquid and hence cannot
ignite itself due to electrical sparks and cause an explosion.
LOW FUEL SENSOR
A low fuel sensor is provide d so that an indication appears in the MIL if the fuel in the
tank is less than 2.5 litres.

MALFUNCTION INDICATOR LAMP (MIL)
Assembled on the headlamp casing
Malfunction or abnormalities in any of the EFI components (sensors) is indicated by MIL
located on the right side on the headlamp casing. When the ignition key is switched on, the
stop switch is in RUN position & the side stand is retracted, the MIL will glow for few
seconds, which indicates that the ECU is checking the vital functionality of the sensors. In
case of any fault, in the system the MIL will remain “ON” continuously.
Specification:
Operating Voltage : 12 V.
Bulb Rating : 12V, 4W.
