5.9L Common Rail Owners, Please note:
The number one cause of premature 5.9L CR fuel system failure is contaminated fuel. Due to the high pressures and extremely fine tolerances involved these systems are much more sensitive to water and particulate matter than earlier fuel systems. Compounding this is the undisputed fact that the filtration system on these trucks is woefully inadequate. A single tank of bad fuel can and often does cause catastrophic fuel system failure both the CP3 pump and the injectors can be affected.
Failure to completely clean and flush contamination from the fuel supply system before replacing parts WILL result in repeat failures. We have seen repeat failures occur before the vehicle is physically able to leave the repair facility where new parts were installed.
Before installing any new fuel system components we recommend disconnecting the fuel supply line from the CP3 pump and activating the electric fuel pump by turning on the ignition while collecting the fuel in a clean glass sample container. Ideally this fuel should be sent to a lab for analysis. At a minimum, set the sample container aside to settle and then check for any water separation or particulate matter under a bright light. ANY signs of contamination require complete fuel system cleaning.
To properly clean the fuel system the tank must be removed, emptied, and flushed with clean fuel. Do not use water to flush the tank. If the tank cannot be cleaned completely, it MUST be replaced. Fuel lines must be flushed thoroughly, then inspected. If rusty inside, they must be replaced. The fuel filter must be replaced regardless of whether or not contamination is found in the fuel system.
Please take this seriously contaminated fuel CAN happen to you regardless of where you buy your fuel or how long you have purchased it there.
