Fits: 2017 thru 2019 Chevy Silverado/GMC Sierra 2500HD/3500HD L5P Duramax Diesel (Requires Tuning)

Finally! A Duramax comes from the factory with a lift pump! Unlike the 2001-2016 trucks, once the L5P was launched, in 2017, they came with a lift pump. This is a great step forward, it still falls a big short, should you plan on hopping up the truck power-wise. The FASS Titanium Signature Series 140GPH will provide enough pressure and volume to support up to 500HP. Not to mention, MUCH better filtration than stock, which is imperative to protect the costly HP4 Injection Pump and Fuel Injectors. Comes with everything you need for install.

REQUIRES CUSTOM AFTERMARKET TUNING: If the truck is not equipped with an aftermarket tune and the ability to delete specific codes, the vehicle will have a MIL after the FASS installation. Consult with your calibration supplier PRIOR to the FASS installation to confirm they are able to delete specific diagnostic codes.

If the truck is not equipped with an aftermarket tune and the ability to delete specific codes, the vehicle will have a MIL after the FASS installation. Consult with your calibration supplier prior to the FASS installation to confirm they are able to delete specific diagnostic codes.

The Titanium Signature Series diesel fuel systems are the superior fuel pump and filtration system, in the diesel industry.  This is because here at FASS Diesel Fuel Systems we focus on perfecting our pumps and how they are engineered, taking the extra steps that our competitors ignore while they rush to get product out the door.  By doing this we have less than a 2% failure rating with our motor and a design that implements unique design features you can only get with FASS Diesel Fuel Systems

• FASS Whisper Technology (FWT) was engineered to meet the stringent demands of  today’s quiet diesel engines. FASS Whisper Technology was in development and testing for over two and a half years to meet FASS Fuel System’s high quality and durability standards. FASS Whisper Technology effectively and drastically reduces the sound levels of the Signature Series FASS Diesel Fuel System to a “whisper” while at the same time increasing fuel flow rates. Our competition reduces noise levels by reducing flow rates.
• Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the FASS System by creating smooth flowing cuts within the aluminum housing.  This prevents the reintroduction of air and vapor back into the fuel and to prevent eddy currents from forming within the corner of a 90-degree sharp angle. FASS Titanium Signature Fuel Systems 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 to prevent cavitation along with galling and scoring. Then 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 “Polished” (cleaned), guaranteeing that your diesel truck always has the cleanest fuel possible. The MFR in combination with the optional FASS Fuel Heater options will help insure “EXTREME” cold weather operations!
• Bolt On Bracket Mounts old mounting styles required drilling or welding when mounting your new pump.  This has now been simplified with our new bolt on brackets that utilize your Ford Super Duty factory bed bolt, the bolt that secures your truck bed to your frame. Mounting your Titanium Signature Series lift pump takes only minutes and all brackets are made from machined steel for superior support and strength.
