Adjustable High Flow Fuel Pump With Race Ready Precision

The FASS FASC09100G Adjustable Fuel Lift Pump is engineered to give performance Duramax owners precise control over fuel delivery. Flowing 100 gallons per hour and adjustable from 1 to 20 PSI, this pump allows you to tailor fuel pressure to match your specific tuning, turbo, or injector setup. It uses the same high-quality motor found in the Titanium Signature Series, offering long-lasting performance in a compact, standalone package. The built-in boost compensation port helps maintain steady fuel pressure under high load by reacting to intake manifold pressure changes, ensuring fuel is delivered consistently at wide-open throttle. This setup is ideal for competition or heavily modified trucks that still use the factory fuel filter system. It’s important to pair this pump with a quality fuel pressure gauge when making adjustments, to avoid over-pressurizing the system. With smart design and race-ready features, this FASS unit provides dependable fueling for high-demand diesel applications.
