FUEL DELIVERY SYSTEM - K SERIES KV6

DESCRIPTION AND OPERATION

19-3-7

Operation

The fuel pump is controlled by the Engine Control Module (ECM), which switches the fuel pump relay in the engine 
compartment fuse box to control the power feed to the pump. The electrical circuit for the fuel pump incorporates an 
inertia fuel cut-off switch attached to the LH front suspension turret. In a collision above a preset deceleration speed, 
the switch breaks the circuit to the fuel pump to stop the delivery of fuel to the engine. The switch is reset by pressing 
the rubber top.

WARNING: Ensure there are no fuel leaks and confirm the integrity of the fuel system before resetting the fuel 
shut-off switch.

The fuel pump outputs more fuel than the maximum load requirement of the engine, in order to maintain a constant 
pressure in the fuel rail under all running conditions.
