The Duramax diesel from the factory is not supplied with a factory lift pump like other truck manufacturers. Upgrading your fuel system is a must in a Duramax! It is highly recommended that you add a lift/supply pump when doing this upgrade, especially if you are also adding a performance fuel pump. THIS IS AN AFTERMARKET REPLACEMENT. MEETS OR EXCEEDS OE.
