2017 6.7 Powerstroke.

DEF Contamination to fuel system.

Injector and Injection pump damage is not the only victim. The fuel supply system must be addressed as well. 

Considerable changes to fuel supply and filtration on late modern diesel engine. Not just 2 lines any longer. removal and flushing is required. 

Filtration module removed from fuel cell. 

Fuel Cell removed and thoroughly cleaned with detergents and hot water.

Fuel sample from cell notice color and deformation of filtration.

DEF Contamination on filter media. This Contamination traveled through entire low pressure and high pressure system. 

New injectors, injection pump, lines, filtration, and return system has been installed. 

Finalize repair by re-programming Injector Quantity Adjustment. Failure to do so will result in poor engine performance.
