S&S 6.7L Ford Power Stroke CP4 Fail Safe Kit

6.7L Ford Power Stroke CP4 Fail Safe Kit helps prevents the disastrous consequences of an inevitable CP4 pump failure from destroying the rest of a very expensive high-pressure fuel system.

CP4 high pressure pumps are the Achilles heel of the 6.7L Ford Power Stroke engine due to high failure rates, which commonly take out the entire very costly high-pressure system with it (injectors, rails, lines). When the CP4 fails, it sends debris into the rest of the system and requires a several thousand-dollar replacement of injectors, rails, lines, etc. The S&S Fail Safe Kit reroutes the pump bottom end flow back to the tank and filters and helps prevent the CP4 debris from getting to the rest of the high-pressure system.

  • Keeps injectors/rails safe from CP4 pump failure debris
  • The original 6.7 Power Stroke CP4.2 bypass kit
  • 50state CARB-compliant (EO number D-756-1)
  • 100% Made in the USA
