FASS TSPC11100G Titanium Signature Series Plus 100 GPH Diesel Fuel Lift Pump System

The FASS TSPC11100G Titanium Signature Series Plus is a premium diesel fuel lift pump and filtration system engineered to deliver exceptional performance, longevity, and reliability for GM Duramax 6.6L engines. This next-generation fuel system combines advanced air and fuel separation technology with superior filtration to protect your injection system and maximize engine performance.

Key Features:

• 100 GPH (gallons per hour) flow rate supports stock to 600 horsepower applications
• Advanced 2-micron absolute filtration removes harmful contaminants, water, air, and vapor
• ORB (O-Ring Boss) fittings with 6061 black anodized aluminum construction for durability and clean aesthetics
• Black fuel lines provide an ultra-clean, professional installation appearance
• FASS Whisper Technology (FWT) reduces operating noise while maintaining high flow rates
• Performance Radius Cuts (PRC) prevent air reintroduction and optimize fuel flow
• Mass Flow Return (MFR) technology continuously polishes fuel by maintaining positive pressure
• Bolt-on mounting brackets utilize factory bed bolts for easy installation without drilling or welding
• Backed by FASS limited lifetime warranty for peace of mind

Duramax diesel engines lack a factory lift pump, forcing the CP3 or CP4 injection pump to pull fuel under vacuum—adding stress and risking air introduction. The TSPC11100G eliminates this problem by providing clean, pressurized fuel delivery. This system removes over 99% of water, air, and vapor while improving fuel lubricity, resulting in better throttle response, increased horsepower and fuel economy, extended injector and injection pump life, and reduced DPF and EGR system wear.

The Titanium Signature Series Plus represents the pinnacle of FASS engineering, with less than 2% motor failure rate and proprietary features unavailable from competitors. Perfect for daily drivers, work trucks, or high-performance builds seeking reliable fuel system protection.
