CP4 Fuel Block: Essential Upgrade for Super Duty Trucks

Ford Super Duty trucks get the job done. But they have a factory fuel-routing design that simply doesn’t make sense.

The Make Sense Block reroutes your fuel in a way that actually makes sense—and installs in just a few minutes.

It's a quick, engineered upgrade that takes the nightmare out of a 6.7 diesel powerstroke fuel system.

  • The Problem

    Metal debris from the cam or rollers in the factory CP4 pump gets ingested into the high-pressure poppets, leading to a catastrophic and devastating complete fuel system failure.

  • Why It Happens

    The fuel has to act as a lubricant before it is compressed to close to 30,000 psi and injected directly into the cylinder to make horsepower. 

  • The Solution

    The Make Sense Block takes the hot aerated fuel from cavitation bubbles is sent directly back to the tank before it is allowed to mix with the fuel entering the CP4. This ensures only cooler, denser fuel is used to lubricate the pump—protecting your investment and keeping you out of the repair shop.
