This pump is the perfect upgrade over the stock CP3 pump for those looking to gain more horsepower and torque when their trucks are turned up with tuning and other supporting modifications. You do not have to waste your time looking at competitors "modified" CP3 pumps, this pump by S&S Diesel Motorsport, will continue to flow past the stock drop off level. The stock GM CP3 is only capable of flowing fuel up to 3000 rpm and begins to fall off, where the Sportsman pump will continue to flow until 4500+ rpm. This is the perfect and most affordable solution for a "true" tested and modified CP3 pump that won't require big air and fueling modifications in order to work
*Can be used in LB7-LML, tuning will be required for most model years.
