Rochester 4G Carburetor Accelerator Pumps

Upgrade your Rochester 4G/4GC carburetor with our new high performance ethanol resistant Four-Jet accelerator pump assemblies and accelerator pump cups.
Note: There are several versions of ethanol "Blue" accelerator pump cups, we only sell the ones that work the best.

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.
