The Duramax engine is extremely capable of adding a substantial amount of horsepower all while being exceptionally reliable. What truly holds back the entire system is the lack of a factory lift pump. The fix? Upgrading with a FASS. The Titanium Series fuel system from FASS has long been hailed as the benchmark in a reliable lift pump for your Duramax. And with over two years in development, FASS was able to improve upon this design and released their Signature Series Titanium featuring new advancements to include their Revolutionary Whisper Technology for a dependable pump without the noise. This particular 250GPH model is rated for 900 to 1200 horsepower.

A FASS Fuel Systems can be a beneficial upgrade for your GM Duramax diesel engine, this is because your Duramax doesn't come with a factory lift pump like other diesels from the factory. This requires your CP3 (2001-2010 models) or CP4 (2011-2016 models) injection pump to pull your fuel under a vacuum, adding additional stress to your injection pump and risk introducing additional air into your fuel. This is where a Titanium FASS Fuel Pump comes in to help.

The Titanium Series diesel fuel lift pump was engineered by FASS Fuel Systems to be the top performing, longest lasting, and most reliable aftermarket filtration system in the diesel industry. Rated at 250 gallons per hour and backed by a limited lifetime warranty, the Titanium Series lift pump is capable of supporting your GM Duramax 6.6L diesel engine with enough fuel for multiple fueling system upgrades. 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. These benefits include an improved filtration rating of 3 Microns, a built in water separation filter, and FASS Fuel Systems patented air/vapor removal process. Duramax diesel engines are known for having injector failure issues; this can be caused by several different factors and FASS Filtration Systems is designed to eliminate those that are fuel related.

This kit includes a FASS STK-1002 (Bulkhead and Suction Tube Kit). Machined from 6061 T-6 Billet Aluminum, the Bulkhead fitting functions as both a suction tube and return and features a 5/8" Suction Tube along with a 1/2" Fuel Return Port. This new and improved version from our previous Suction Tube Kit allows the user to plum their FASS return line directly to their bulkhead fitting, eliminating all cutting of the filler neck, and significantly speeds up the installation process. The pickup tube is fabricated of PTFE Teflon which can be easily cut to adapt to different depth of fuel tanks. Properly installed, you can safely operate down to about 1/8 tank of fuel.

FASS Silencing Technology (FST) was developed by the engineering team at FASS Fuel Systems to help reduce the noise created by aftermarket fuel and air separation diesel lift pumps. By using radius cuts, tighter tolerances on all gears and a high-quality military specified coating over the aluminum base, FASS Fuel Systems was able to develop the quietest fuel air separation system on the market.
Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the diesel lift pump by creating smooth flowing cuts within the aluminum housing. This prevents the reintroduction of air and vapor back into the fuel and also to prevent stagnate fuel pockets from forming within the corner of a 90-degree bend. FASS Fuel Systems Titanium Series Diesel Fuel Pumps are the only Fuel Air Separation System that incorporates these exclusive Performance Radius Cuts, lesser competitors commonly use T-Bone and square 90-degree fittings that can limit fuel flow, cause restrictions, and reintroduce air back into your fuel.
Mass Flow Return (MFR) technology is used to continually "polish" your fuel by keeping a positive pressure on the fuel being delivered to the engine and returning the fuel that's not yet needed back to the tank after it has been passed through the filtration process, removing dirt, air, vapor, and water. This means your fuel is being constantly moved and cleaned, guaranteeing that your diesel truck always has the freshest and cleanest fuel possible.
Bolt On Bracket Mounts are another huge benefit to the Titanium Series lift pumps. Old mounting styles required drilling or welding when mounting your new pump. This is simplified with bolt-on brackets that utilize your Dodge Cummins factory bed bolt, the bolt that secures your truck bed to your frame. Mounting your Titanium Series lift pump takes only minutes and all brackets are made from machined steel for superior support and strength.
