The Industrial Replacement FCA is designed specifically for the 2001–2004 GM 2500HD and 3500HD with the 6.6L Duramax LB7, offering a reliable and direct replacement solution when the factory FCA starts to fail. Mounted to the back of the CP3 pump, the FCA plays a crucial role in regulating how much fuel gets delivered into the injection system. When it’s not functioning correctly, it can throw off the entire fuel delivery strategy of your truck, leading to performance loss and drivability issues. That’s where this Industrial Injection unit steps in. It restores consistent fuel pressure and smooth operation without requiring any tuning or complex reprogramming—just plug it in and get back on the road.
