First off nothing wrong with thinking outside the box. Unfortunately though, what you are proposing will have no benefit whatsoever my friend and here's why. The OEM fuel pump (/HFCM as some people call it) is only responsible for filling the injectors with fuel to be injected into the motor. The High Pressure Oil Pumping System is what is responsible for actually injecting the fuel into the motor via hydraulic oil pressure. CP3 pumps do both filling the injectors and injecting the fuel into the motor. However, the common rail injection system is vastly different from our injection system. What you are actually thinking of (and kind of applies) is dual High Pressure Oil Pumps (HPOPs). These provide more oil flow to the injection system and in essence is the closest thing you can do on motors that would be like a dual CP3 setup. However though, you wouldn't really see any gains unless you were running (at a minimum) a 190/100 or 205/100 injector. Basically, for 225s and above, you could possibly look into something like this. Either way though, higher injection pressure does give better atomization of the fuel for a better burn and more power. Hope this helps some.
