The Snow Performance high-output fuel hat for 2019+ GM half-ton trucks and Denali models is a billet-aluminum, drop-in replacement manifold that accepts configurable two- or three-pump setups using genuine TI Automotive (Walbro) pumps in 450 or 470 LPH options. It’s a return-style assembly only, compatible with gasoline and ethanol blends (not methanol), and retains the factory sending unit and EVAP features.
