6.7L Ford Powerstroke CP4 Injection Pump Failure #1 Diagnosis

This is the first of two back-to-back failures we recently saw on the 2011-2017 6.7L Ford Powerstroke Bosch CP4.2 high pressure injection pump. Initial analysis points to water in the fuel, as the Fuel Press Control Valve (FPCV) and Fuel Volume Control Valve (FVCV) were both heavily rusted. This water contamination resulted in catastrophic failure of the high pressure injection pump due to the water's displacement of the diesel fuel which provides the lubrication and cooling of the pumps cam and rollers located within the pump crankcase. Due to a design flaw from Ford, this debris from the pump's crankcase was then sent to the high pressure side of the pump, subsequently pressurized, and sent out the the fuel rails, all eight injectors, the return lines, fuel cooler and back to the tank before it was eventually drawn back through the primary filter within the Diesel Fuel Conditioning Module (DFCM) and the engine mounted secondary filter. The end result was complete destruction of the high pressure fuel system resulting in a repair bill nearing $9,000!

The Scorpion CP4 Disaster Prevention Kit would have prevented the contamination of the fuel rails and injections, by diverting the debris from the failing cam and rollers directly back to the tank, instead of the inlet to the high pressure pump, thereby saving everything downstream of the injection pump and a whole lot of $$$. Look for our other video containing the innovative and relatively cheap insurance for your 6.7L Powerstroke.

It is our further belief that a FASS fuel/water seperator would greatly prolong the life of the stock CP4 pump by continually filtering out water, dirt and air from the fuel, thereby delivering the highest quality fuel for this application. Also look for our video containing this relatively cheap upgrade for your 6.7L Powerstroke's fuel system that will help your investment last longer with less downtime and expense.

Thanks for watching!
