The Holley 26-41 is an umbrella-style accelerator pump check valve for Model 4150 and 4160 carburetors equipped with a 30cc or 50cc accelerator pump. Seated in the fuel bowl, the check valve controls the one-way flow of fuel into the pump circuit so the pump shot fires cleanly on throttle tip-in. Molded from Viton, it resists the ethanol-blended pump fuels that swell and distort standard rubber valves.
