FASS Fuel Systems Diesel System 2011-2014 GM Duramax LML 6.6L Titanium Signature Series 100GPH (TSC11100G)

Part No: TSC11100G

A FASS Fuel Systems can be a beneficial upgrade for your GM Duramax LML diesel engine, this is because your Duramax doesn’t come with a factory System like other diesels. This requires your CP4 injection System to pull your fuel under a vacuum, adding additional stress to your CP4 System and risk introduce additional air into your fuel. This is where a Titanium FASS Fuel System comes in to help.

The Titanium Signature Series diesel fuel System 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 100 gallons per hour and backed by our limited lifetime warranty the Titanium Signature Series System is capable of supporting your GM Duramax 6.6L diesel engine with enough fuel for multiple fueling System upgrades.  A Titanium Signature Series System also offers advanced filtration benefits that will help protect your Duramax’s injection Systems, effectively extending the life of your Injection System and Injectors. These Benefits include an improved filtration rating of 2 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.

The Titanium Signature Series diesel fuel Systems are the superior fuel System and filtration System, in the diesel industry.  This is because here at FASS Fuel Systems we focus on perfecting our Systems 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 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 System. 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 System takes only minutes and all brackets are made from machined steel for superior support and strength.

NOTE: Installation of this kit on a cab and chassis may require modifications.

It is suggested for this higher performance System to upgrade your System kit by purchasing our Bulkheading and Suction Tube kit (STK1002).  Our 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 GM Duramax application that demand large a large amount of diesel fuel for aggressive fueling upgrades.

Reviews

  • What are the micron ratings of the filters that come with this kit?

    Trev | 4/19/2025

    Filtration rating of 3 micron.

  • Do I have to use the fuel filter delete or can I continue to use my Wix filter for extra protection?

    Tom King | 11/26/2025

    You do not have to delete the stock fuel filter. That option is up to you.

  • Which one would be best for my 2015 duramax 6.6 100 or 165

    David | 4/14/2025

    100 GPH will support 600HP, 165Gph UP TO 800HP.

  • IS the FASS 165 a flow through design? If the pump fails, is it going to leave me stranded?

    Adam Thomas Giberson | 3/17/2022

    Yes.

  • Do I need to buy a sump for the fass 165 or will my draw straw suffice?

    Kyle | 11/30/2020

    Sump is not required, and Draw straw will work.

  • Is this just the lift pump or is it the whole kit

    Zach | 5/21/2019

    This is everything you need for installation.  Lines, wiring, pump, mounting, etc.

  • Installed new fass no fuel coming out of #1,3 injector lines with the pump running is this normal? If I have it running it sprays fuel out at the injector where I have it loose at. I have a fass 165.

    Man Peavy | 5/30/2022

    What vehicle do you have?

  • Are these pumps strictly for diesel only?

    Wallace | 5/27/2020

    Yes

  • Does FASS void factory manufacture warranties?

    Anthoy Davis | 5/22/2019

    No, FASS does not void factory manufacturer warranties because our products meet their filter specifications.

  • Will my fuel mileage increase?

    Meredith Clark | 5/22/2019

    After the installation of the Titanium series unit, our customers have reported 2-3 mpg increases for pickups and .4 mpg increases for Class 8. While this is an average, FASS does not guarantee fuel mileage increases.

  • Can I install the FASS system myself or does it need to be installed by an authorized FASS dealer?

    Todd Flowers | 5/22/2019

    FASS is continuously updating and changing our units to make them easier to install for the end user.
