We have upgraded all of our kits to use the latest design accellerator pump assemblies. They come with our custom wound duration springs, and matching return spring. The pumps use the latest design seal with garter spring, ethanol resistant, and insure maximum fuel delivery.
They are available separetely from our kits as complete assemblies, and replace all earlier designs. We will cut the accellerator pump groove on them per request, for the Pontiac Ram Air carburetors, at no additional charge.......Cliff
