2005 Chevrolet 6.6L Duramax LLY
(Showing )

Description
Your 6.7L Powerstroke has a fuel system basically consisting of a CP4 high pressure pump and low pressure pump that supplies fuel from the fuel tank to the injectors, and a filter. If this type of system sounds familiar, that's because its essentially the same principle that all light duty diesel pickups of this era run. The reasoning everyone uses this design is because the system can be nearly completely electronically controlled via the ECM in an effort to maximize power while minimizing emissions. Overall, this type of fueling is light years ahead of older, previous designs, but still has drawbacks in long term durability and in horsepower building potential. We offer numerous upgrades that can both assist in extending the longevity of your fuel system, as well as assisting in reaching your horsepower goals.
As always, if you have any questions about which product is right for you and your truck, do not hesitate to give us a call or send an e-mail to cs@dieselpowerproducts.com and we would be happy to assist.
