Double Pumper carburetors are an American icon when it comes to performance carburetors. From their roots as the premier carburetor on many factory muscle cars to powering thousands of vehicles across the finish line, the Double Pumper is a great choice whether you are burning up the street or the quarter mile.\n\nThe Ultra Double Pumper™  Carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061-T6 billet aluminum. They weigh in at approximately 5 lbs. less than a comparable zinc carburetor.\n\nThe 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, dual accelerator pumps for additional fuel under initial acceleration, 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.\n\nThe clean, polished look coupled with Black metering blocks and throttle body will certainly set your ride apart whether you are at the show or track.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eShiny with black anodized billet aluminum metering blocks\/base plate for good looks and true gasket sealing\u003c\/li\u003e\n\u003cli\u003eUltra Double Pumpers feature an Optimized street\/strip calibration that works out-of-the-box\u003c\/li\u003e\n\u003cli\u003eFactory preset electric choke for easy startups\u003c\/li\u003e\n\u003cli\u003eMechanical secondaries for awesome tire turning performance\u003c\/li\u003e\n\u003cli\u003e4 corner idle allows you to precisely control your idle system\u003c\/li\u003e\n\u003cli\u003eBuilt in, clear fuel level sight glass for easy, no mess fuel level adjustments\u003c\/li\u003e\n\u003cli\u003eAluminum construction for a 43% weight savings\u003c\/li\u003e\n\u003cli\u003eCompatible with GM, Chrysler, and Ford A\/T kickdown linkage.
