Rochester 2 Jet Accelerator Pumps
Ethanol resistant. The Rochester 2 Jet carburetor can use several different accelerator pumps. Matching your carburetor number is the best way to insure you are getting the correct accelerator pump, otherwise you will need to match the sizes. The Rochester 2 Jet uses either a 3/4", or 21/32" diameter cup. The other measurement is the overall length and that is measured using decimal (outside caliper).
