2G Carburetor Accelerator Pumps

Upgrade your Rochester 2G carburetor with our new high performance ethanol resistant Two-Jet accelerator pump assemblies and accelerator pump cups.
There are 2 different diameter accelerator pump cups 21/32" and 3/4". Identify the correct pump assembly by matching your carburetor number. If carburetor number is not know or available, measure the cup diameter and overall (tip to tip) length of your old pump and select closest match.
