stage three cp3

was wondering if the stage 3 pump is a direct fit and what kind of flow does it have

We don't classify our pumps by stages. We offer a Duramax and a Cummins CP3, in different levels. 15% to over 70% above stock, no BS. We are hoping to have our new test stand up and running soon to verify these numbers. Been too busy in other areas of pump development to stop and finish. We will post the numbers for all of our CP3 products then.
