The 6.7L Powerstroke uses a CP4 that has a high failure rate &, when it fails, sends metal debris through the high pressure fuel system. Prior to failing, there are no warning signs; it just happens. And it can happen at any time! When this happens, the ENTIRE high pressure fuel system needs to be replaced, costing upwards of $10,000!
The CP4 cannot be replaced with a more reliable CP3, so the only option is to reroute the fuel. This kit reroutes the fuel (and potential debris) back to the fuel tank so that all of the fuel entering AND leaving the CP4 goes through the fuel filters to catch any debris before heading off to the rest of the high pressure fuel system.
This kit is great insurance against a common disaster and can save you THOUSANDS!
