FASS suggests that if you're close to 550 to 600 horsepower to upgrade this lift pump by purchasing their Bulkhead and Suction Tube kit, part number STK1002. This bulkhead kit allows for a larger volume of diesel fuel to be retrieved by the fuel system and will offer a convenient return option. This is important for high performance Duramax applications that demand large a large amount of diesel fuel for aggressive fueling upgrades.

FASS Titanium Fuel Systems are an important upgrade for Duramax diesels because they don’t come with a factory lift pump like other diesels. This requires the CP3 or CP4 injection pump to pull fuel under a vacuum, adding stress to the pump and risking introduction of additional air into the fuel. Duramax diesel engines are known for having injector failure issues. Although this can be caused by several different factors, FASS Filtration Systems eliminate those that are fuel related. A Titanium Series lift pump also offers advanced filtration benefits that will help protect your Duramax’s injection systems, effectively extending the life of your Injection Pump and Injectors.
