To repair the failed pump and avoid the risk of contaminating the replacement parts, all the components mentioned must then be replaced. Trying to flush the fuel system doesn't ensure that all the remaining metal shavings or debris will be removed from the system.
The UnderDog Diesel Fuel Contamination Kit is excellent replacement for your Powerstroke engine with a failed CP4 fuel injection pump, DEF contamination, or water in the fuel tank. This UnderDog Fuel Contamination Kit comes with all the major pieces you need to get your truck back on the road.
Other components included with this kit are fuel injectors, fuel injector lines, fuel rails, and many more parts. Swapping out all of these components will help ensure that all the injection pump debris are out of the fuel system.
This will make sure that the replacement components won't get contaminated from the previous pump failure.
The CP4 high-pressure fuel pump in 2011 to current Ford Super Duty diesel trucks has a well-earned reputation for failing without warning, creating sudden power loss, and taking out the expensive high-pressure fuel system in the process. Despite having to deal with being broken down on the side of the road, truck owners will be facing fuel system repairs that can easily exceed $10,000. The unreliable reputation is supported by recalls and lawsuits leveled at various auto manufacturers that use the CP4 in their production vehicles. S&S Diesel Motorsport™, the common rail diesel injection experts, teamed up with PurePower Technologies, Inc.®, the aftermarket division of longstanding fuel system manufacturer, Stanadyne®, to do the impossible. Collectively, they solved the widely-known CP4 fuel pump problem plaguing Ford Super Duty trucks using the 6.7L Power Stroke diesel engine.
