01-10 Duramax FASS Titanium Signature Series PLUS 165GPH Fuel System-1000HP

FASS Titanium Signature Series Plus 165GPH Lift Pump (01-10 Duramax)

If you’re building a higher horsepower Duramax and want a lift pump that can actually keep up, the FASS Titanium Signature Series Plus 165GPH system is the move. This is the updated Signature Series system built with ORB (O-Ring Boss) fittings, black anodized 6061 aluminum fittings, and black fuel line for an ultra clean install.

Rated at 165 gallons per hour, this system is designed to support up to 1000 HP — ideal for larger injectors, upgraded CP3s, compounds, or anything that needs steady fuel supply under heavy load.

The 165GPH system also works great on stock trucks, and it gives you plenty of room to grow as you add power later.

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.
