3) High pressure pipe (fuel pipe)
Fuel line transfers high pressure fuel. Accordingly, it is made of steel to endure intermittent high
frequency pressure changes that occur under maximum system pressure and injection stops.
Injection lines between rail and injectors are all in the same length; it means the lengths
between the rail and each injector are the same and the differences in length are compensated
by each bending.

The fuel injection device is composed of
electrical solenoid valve, needle and nozzle
and controlled by engine ECU. The injector
nozzle opens when solenoid valve is
activated to directly inject the fuel into
combustion chamber
injector nozzle is open, remaining fuel after
injection returns to fuel tank through return
line.
Pressure limit valve, fuel returned by low
pressure and fuel used for high pressure
pump lubrication also return to fuel tank
through return line.
The transfer pump is included in the housing
of the high pressure pump. The transfer
pump is the volumetric blade type pump. To
deliver the continuously
volume, the pump transfers fuel from the fuel
tank to high pressure pump.
