Improve performance with AED jet extensions. Virtually all single carbureted drag cars need rear jet extensions. During acceleration and high g-forces, fuel is pushed to the rear-most portion of the float bowl, uncovering the jets and creating a lean condition, which reduces performance. AED's bored stainless steel extensions have a special half-moon shape that ensures plenty of fuel volume and clears the stock floats.
