Product Description



Consider that typical No. 2 Diesel Fuel consists of about 10% air. This fuel problem is compounded by dirt and other debris that can be found in a diesel fuel tank. Without a way to filter your fuel, at some point in the future you can expect to have expensive repairs of injectors, injection pumps and other fueling components. FASS Titanium Fuel Systems address these issues head on by meticulously filtering out such problematic air & vapor — along with other contaminants in the fuel — before it’s sent to your truck’s injectors. The Titanium Signature Series diesel fuel lift pump featuring their Revolutionary Whisper Technology was engineered by FASS Fuel Systems to be the top performing, longest lasting and most reliable aftermarket filtration system in the diesel industry.

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.



Obsessed with providing the absolute best conditioned fuel to your diesel engine, FASS Fuel Systems has an entire R&D team developing solutions to the problems that contaminants in diesel fuel wreak upon your truck. Along with The Association of Diesel Specialists and other diesel industry leaders, they recognize the severity that problems with the fuel supply — including air/vapor in fuel — can cause. From FASS, here is just the short list:

  • Low Horsepower
  • Low Fuel Mileage/Poor Fuel Mileage
  • Excessive Smoke
  • Injector Failure
  • Hard Start or Will Not Start
  • Engine Surges at Low Idle
  • Warm Engine Runs Rough or Misfires in Operating Range
  • Rough Idle
  • Engine Will Not Reach Rated Speed When Loaded

FASS’ Mass Flow Return (MFR) technology is used to continually “polish” your fuel. It does this by keeping a positive pressure on the fuel being delivered to the engine and returning 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, guarantying that your diesel truck always has the freshest and cleanest fuel possible.
