Want this question answered?
If the question is how is it delivered ,then this how by transfer pump to the high pressure injector pump then through the nozzles.
ITS ON TOP OF THE PUMP.
The 3 series BMW uses a common rail diesel injection system. This means a high pressure pump provides diesel to a common rail feeding all 4 injectors. If one injector goes down there can be insufficient pressure to start the car. The 3 series BMW uses a common rail diesel injection system.

Fuel pressure pump, gets fuel to fuel injector pump, which pump do you want to check and symptoms?
Injector timing on b6000 is adjusted by adding or subtracting shims under the injector pump. Timing should be set with fly wheel timing mark on cyclinder #1
transfers fuel to injector pump from tank
The fuel injector pressure regulator is located in the injector fuel pump. Most pressure regulators cannot be separated from the fuel injector pump.
in appropriate injector's, clocked injector nozzle's, injector pump diaphram ,(due to dirt fuel)
Lift pump failing and then taking out the injector pump
Your engine does not really have an injector pump. It has a fuel pump that feeds the fuel filter and then into the fuel rails. The pressure oil pump increces the fuel pressure in the injector and the enjector is opened electricly. This is a very simple way of telling you how it works. The height pressure oil pump is located at the front of the engine under the fuel filter just below the oil tank.
Common rail diesel basic description:A common rail diesel engine differs from a conventional diesel engine in several important respects. A conventional diesel engine works via a mechanical injection system, which relies on the engine's diesel injection pump to deliver the required fuel pressure, at the correct time, to the diesel injector in order to allow the injector to operate. Each individual injector on a conventional diesel engine has its own pipe or "rail" connecting the injector to the mechanical pump, allowing the delivery of fuel to the injector. Common rail diesel injection systems work on a much different principle. In this system the mechanical controls are replaced by electronic controls to allow for more precise metering and timing of the fuel delivery into the engine, and therefore the injection pump is no longer solely responsible for the operation of the injection system. Also, the individual injector rails are replaced by 1 (or 2) "common rail" which operates under a constant high pressure. There is no injection pump associated with this system, yet a high pressure pump is still required to deliver the high pressure fuel to the common rail. The high pressure pump is capable of producing (depending on the system used) approximately 29000 psi of pressure into the common rail. At the correct time the electronic injector is operated and the fuel is injected into the engine allowing ignition to occur. The timing and fuel quantity is controlled by an advanced engine management system which gathers data on the engine conditions via a collection of sensors. All of these sensors measure different system parameters to calculate the correct fueling for the engine at any given moment.
The fuel pump is part of the injector pump, althoug many diesel vehicles have a separate lift pump in the fuel tank as well.
