Because it has a built in supply pump, the CP3 only needs to be supplied at a low pressure OR VACUUM and it will handle supplying the pumping chambers from there. Users needn't worry about pushing fuel to a CP3 at a high pressure. Conversely, if there isn't enough flow to it, the pressure will drop and the supply pump may actually start developing a vacuum in an attempt to get enough fuel. There are no internal relief valves in the CP3, only a direct feed to the supply pump. If you try to push too much fuel to the CP3, the pressure will skyrocket. Whereas an injection pump like a P7100 can tolerate a large difference in flow rates to/through it with relatively little pressure change, the CP3 cannot. It actually does this on Duramax installations.īeing a constant displacement pump means that it you can't hook just any supply pump up to it. This pump is actually capable of developing enough suction to draw fuel through a filter right from the tank. the internal supply pump is a constant displacement gear pump.

Unlike other pumps where the fuel supply pump inlet may feed the interal cooling passages and make its way back to the return line.īTW: The Dodge shop manuals say the COFV isn't "field serviceable" they have been removed before, disassembled and re installed with no problems. The inlet feeds the internal supply pump. Note that this prioritization happens AFTER the internal supply pump and there is NO passage from the CP3 inlet to the CP3 return line. Any more flow than that and some fuel will get sent out the return line.
If the flow rate increases, the pump will get cooled.
No cooling or return flow will be provided.
If the flow rate is low, only the FCA will get fed. The COFV prioritizes the flow in that order. The cascade overflow valve's (COFV) purpose is to prioritize the fuel flow between the pump itself (ie feed the FCA), then flow excess fuel to the lubrication flows to cool and lubricate the pump and finally divert any flow above that to the return line. This fuel is fed to the FCA via the cascade overflow valve located on the side of the pump. This pump takes the fuel at supply pressure and boosts it to pressures between 80 and 180 PSI depending on what is required. In order to meter the fuel into the chambers, the CP3 has an internal metering/lift pump built right into it. The FCA meters how much fuel actually gets pressurized in the first place. This is in sharp contrast to other pressure control systems that divert large amounts of PRESSURIZED flow OUT of the pump back to the tank. By metered inlet that means that the Fuel Control Actuator valve controlled by the ECM meters fuel going into the pumping chambers to control how much fuel the CP3 pumps and thus the engine rail pressure. The CP3 is a 3 piston metered inlet pump. The fuel injection pump on the 3RD gen Dodge/Cummins is a CP3, this is the same pump used by the Duramax Diesel, If you own a 3RD gen Dodge you need to understand this. I am asking for a D-max guy to help me understand how the CP3 fuel pump works in their application without the use of a lift or pusher pump.
