FAQ
Does this replace my factory fuel filter?No. The FASF16250G is an adjustable lift pump and retains the factory fuel filter. For dual-filter aftermarket systems, see TSF16250G.
What horsepower range can 250GPH support?
Commonly used on ~900–1200 HP builds when matched with proper fueling, tuning, and injectors.
Do I need a gauge to set pressure?
Yes—use a fuel pressure gauge when adjusting the 1–75 PSI range to protect your injection system.
Is there a quieter option?
This pump uses FASS Whisper Technology for low-noise operation. For full filtration and pressure-side water separation, consider TSF16250G.
