Pump-High Pressure Fuel: Description

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: High pressure fuel lines deliver diesel fuel under extreme pressure from the injection pump to the fuel injectors. This may be as high as 1600 bar (23,200 psi). Use extreme caution when inspecting for high pressure fuel leaks. Fuel under this amount of pressure can penetrate skin causing personal injury or death. Inspect for high pressure fuel leaks with a sheet of cardboard. Wear safety goggles and adequate protective clothing when servicing fuel system.

The high pressure pump (1) is mounted to the front of the left bank cylinder head.

NOTE: The high pressure pump must not be disassembled or opened. The only serviceable items are the temperature sensor and the fuel quantity solenoid.
CAUTION: Cranking the engine for an extended time without a fuel supply may damage the high pressure pump.
