If your Duramax demands fueling, there's no better way to provide it than installing an ATS Twin Fueler Kit. By installing a second CP3 to your engine, you will reduce the necessary load on your factory single pump, or even upgraded single pump, by allowing two stock pumps to handle the load.
NOTE: This kit does not include the necessary second CP3 injection pump. For proper installation, you must source a CP3 intended for a 2006-2007 LBZ Duramax. Please see the Related Products section below for options.
The factory CP4 is designed to be a high pressure pump to increase atomization of the fuel resulting in a better driving experience on the new LML platform. Unfortunately this set up lacks the volume when compared to the previously used CP3 pump, resulting in a limited power band and short cap on power that this vehicle can be pushed to. ATS Diesel has designed this Twin Fueler kit to help you receive the best of both worlds with the fuel volume and pressure you need to maximize your driving experience whether it be daily driving, towing, drag racing, or sled pulling!
