Fuel system parts move more fuel, or move it more reliably, than the factory setup was built to. This one is the Fass FASS Drop-in Series Diesel Fuel System 2020-2026 LM2/LZ0 Sierra & Silverado Trucks, listed to fit the 2020-2026 GMC Sierra 1500.

why this one — On a diesel this is usually a reliability buy before it is a power buy. Match the pump to what the tune actually asks for. DmaxStore lists it at $503.99, and the fitment above is what the listing itself states, not a guess.
