Fuel Level Sensor :
The Fuel level sensor assembly consists of float
and a sensor. Fuel level sensor assembly
provides the signal to indicate the fuel level in
the tank. As the float arm assembly moves with
respect to the fuel level in tank, resistance at
sensor harness varies accordingly.
ROLL OVER VALVE :
The ROV is integrated with Tank unit. The ROV
allows only the flow of fuel vapour and does not
allow liquid fuel to flow from the vent line.
In case of a vehicle roll-over, the venting system is
closed by the Roll-Over Valve which avoids any fuel
leakage.
