Double Pumper carburetors are the perfect performance upgrade for hot streetcars and race vehicles. For use with lightweight vehicles with manual transmissions or automatic transmissions with a high stall and low rear end gears, mechanical secondaries mean your foot controls the opening of the secondary throttle blades.
These Double Pumpers carburetors are known for their mechanical secondaries and dual accelerator pumps.
Dual accelerator pumps provide the additional fuel needed for the transition from idle to full throttle which is awesome for tire melting performance. This carburetor is recommended for light wieight vehicles, vehicles with manual transmissions or with an automatic with a high stall torque convertor, and/or low gears.
