How does CP3 pump work?
In order to meter the fuel into the chambers, the CP3 has an internal metering/lift pump built right into it. This pump takes the fuel at supply pressure and boosts it to pressures between 80 and 180 PSI depending on what is required.
How can you tell the difference between CP3 and CP4 pumps?
Basically whe a cp3 quits working it just quits without exploding. It’s typically a slow decline. The cp4 on the other hand doesn’t have a pinned piston and if it rotates slightly it tends to explode and send tiny bits of metal all through your fuel system.
