HP Pump Fuel Route

The fuel passed through the fuel filter is sent to the transfer pump via the HP inlet pump. this fuel passes through the
transfer pump by the transferring pressure and maintains the predefined value by the regulating valve in HP pump.
Also, this fuel gets into the IMV that controls only the fuel to the high pressure pump.
The below figure describes the pump operations when acceleration and deceleration.
