Edelbrock VRS-4150 Race & Performance Carburetor genuine replacement float set. Shape optimized so fuel slosh during hard cornering, hard braking, and hard acceleration do not push the float up turning off the fuel supply. Notched for use with jet extenders. Nitrophyl material is compatible with gasoline, ethanol, and most common race fuels. 0.125" longer float arm than standard floats for better control of the needle and seat.
