01-10 Duramax FASS Titanium Signature Series PLUS 100GPH Fuel System-600HP

FASS Titanium Signature Series Plus 100GPH Lift Pump (01-10 Duramax)

If you’re looking for one of the cleanest and most reliable lift pump upgrades for your Duramax, the FASS Titanium Signature Series Plus 100GPH system is a proven choice. This is the updated version of the popular Signature Series system, now built with ORB (O-Ring Boss) fittings, black anodized 6061 aluminum fittings, and black fuel line for a super clean install.

This system is rated at 100 gallons per hour and is designed to support up to 600 HP.
If your goal is over 600 HP, we recommend stepping up to a 165GPH system to keep fuel supply and filtration where it needs to be.

The Signature Series Plus does more than feed fuel — it protects your injection system by removing the stuff that kills injectors: air/vapor, water, and debris. With 2 micron filtration and built-in water separation, it helps extend the life of your injectors and CP3 while improving overall drivability.
