The fuel VCV is mounted on the top of the high pressure fuel pump. The VCV is pulse width modulated by the PCM to control…

The PCV is threaded into the rear of the left fuel rail. The PCV is a two wire normally open Pulse Width Modulated (PWM) solenoid.…

The outlet check valve closes while fuel is being drawn in due to a pressure difference on the two sides of the check valve. Once…

The pistons are actuated via the actuating lobes and are returned to rest via spring pressure. The pistons receive fuel from the through a one-…

The high pressure fuel pump is a 2-cylinder design. The main shaft has two actuating lobes. The actuating lobes are offset 180 degrees from each…

The high pressure fuel pump is mounted in the front valley of the engine and is gear driven by the camshaft. The high pressure fuel…

The Volume Control Valve (VCV) controls how much fuel enters the two high pressure pump pistons. The high pressure fuel pump is restricted as required…

The injector low pressure connectors have a dual purpose. First, it is not really a return but a low pressure feed to keep fuel pressure…

A fuel cooler is located on the left frame rail forward of the DFCM. The black fuel line is used for fuel return from the…

The FRT is mounted in the fuel line that runs between the secondary fuel filter and the high pressure fuel pump. It is green in…
