RUST IN THE FUEL SYSTEM The combination of a poor water separator design and a lack of maintenance can spell disaster in a hurry for the 6.4L Power Stroke’s high-pressure common-rail fuel system. Once fuel coagulation occurs in the collection bowl, water is allowed to pass through it and make its way into the fuel system. When water is present in the fuel system it reacts with the metal to form rust. The rust can eventually take out the high-pressure fuel pump, which in turn can send shrapnel through the injectors, which return contaminated fuel back to the fuel tank, effectively trashing the entire fuel system (a cost of $6,000 to $7,500). In cases where debris causes an injector to stick open, catastrophic engine failure is often the result. In these all-out engine failures, it’s not unheard of for the repair bill to top $15,000 or more, which forces many owners to simply walk away from the truck.
