Fits: 2004.5 thru 2005 Chevy Silverado/GMC Sierra 2500HD/3500HD LLY Duramax Diesel 

Having issues keeping rail pressure over 3000 RPM in your Duramax in the mid 500 horsepower range, the Sportsman pump from Exergy is engineered to deliver well past the stock CP3 at higher RPMs. In high fuel demand situations, stock CP3s have a hard time delivering the fuel you need past 3,000 RPM. That is not the case for the Sportsman pump, an ideal upgrade for anyone who wants to keep their truck around the mid 500hp mark, or the person who needs to replace their stock pump with the capabilities to support higher horsepower demands. This pump starts as an LBZ-based pump and then is modified and bench-tested for proper performance by one of the most reputable companies in fuel injection.
