All 2001-2010 6.6L Duramax's need a lift pump! Your Silverado/Sierra doesn’t come with a factory lift pump like other diesel pick-ups which forces the injection pump to "pull" fuel all the way from the tank, creating a vacuum which constantly introduces more air and vapor into your fuel. The Duramax Flow Enhancer creates a positive flow, "pushing" fuel to your injection pump, eliminating vacuum and drastically reducing air and vapor.

The FASS GM Duramax Flow Enhancer is a perfect upgrade for stock engines that are looking to improve performance, fuel mileage and reliability.
