CP4 Fuel Block: Essential Upgrade for Super Duty Trucks
Ford Super Duty trucks get the job done. But they have a weird way of routing their fuel lines that make no sense at all.
The "Make Sense Block" reroutes the fuel in a way that makes sense and only takes a few minutes to install.
Problem
Metal debris from the cam or rollers in the CP4 gets ingested into the high pressure poppets. Leading to a catastrophic failure.
Why
The fuel has to act as a lubricant before it is compressed to close to 30,000 psi and injected into the cylinder to make horse power.
Solution
The hot aerated fuel from cavitation bubbles is sent back to tank before it is allowed to mix with the fuel entering the CP4. Causing cooler denser fuel to lubricate the CP4.
