ULTRA shiny – tumble polished finish holds shine longer
ULTRA strong – billet metering blocks & base plates
ULTRA cool – red anodized billet aluminum metering blocks and base plate

The Ultra Double Pumper Carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061–T6 billet aluminum. Three different anodized color options (Red, Blue, or Black) allow for a personalized look while maintaining the ultra high strength and durability you get from billet. They Weigh in at approximately 5 lbs less than a comparable zinc carburetor.

The new Ultra Double Pumper Carburetors have an enhanced fuel curve for optimum performance, with many more features such as aluminum construction; anodized billet aluminum metering blocks and base plate; 4 corner idle for precise idle control; mechanical secondaries for great performance; clear fuel level sight plugs for easy, no mess fuel level adjustments; Ford automatic transmission kickdown for use on popular Ford transmissions; four vacuum ports for all necessary vacuum accessories; and for the first time on a Double Pumper, factory pre–set electric choke for easy, fast cold start–ups.

The clean, polished look coupled with Red, Blue, or Black metering blocks and throttle body will certainly set your ride apart whether you are at the show or track.
