Adding power to your 2001-2007 Duramax-powered truck means moving more fuel through the injectors. That fuel has to come from somewhere, but a factory original fuel pump might not be up to the task.
Industrial Injection offers this Modified CP3 pump that is a drop-in replacement for the factory Bosch LB7 CP3 pump. The Modified CP3 pump, however, flows 42% more diesel than the stock pump, allowing for 100+ more horsepower depending on how your truck is set up. It’s meant to manage the fuel flow needs of large injectors and aggressive tunes.
All of our Modified CP3 Injection Pumps have our CP3 Technology, Microblue coating along with 60/65 Rockwell Hardness and Black DLC coating.
