The new Ultra Double Pumpers are built to exceed the Coast Guard standards and are J1223 Marine Standard certified. So, if you are hitting the lake for an easy cruise or some high speed fun, these new performance carburetors will meet and exceed your performance demands!

NOTE: This carburetor has square bore flange bolt pattern. It replaces Holley, Edelbrock, Carter AFB & Autolite style carburetors with 5 3/16" x 5 5/8" bolt pattern. If you have a spreadbore style intake manifold, you need an adapter to install this carburetor, similar to Mr. Gasket #1932.
