Smeding Diesel 2011-2018 Ford F-250/F-350 6.7L Powerstroke CP4 Bypass (Disaster Prevention) Kit

The CP4.2 injection pump on the 11-18 6.7 Power Stroke is the truck’s most infamous failure: when it lets go it sends metal through the entire fuel system and turns into a five-figure repair. This disaster-prevention bypass reworks the fuel routing so a CP4 failure can’t take the whole system down with it — the single cheapest thing you can do to protect an expensive 6.7 fuel system. Fits 2011-2018.
