Rochester 4G & 4GC, 4-barrel Carburetor Accelerator Pumps
Ethanol Ready
The Rochester 4 Jet carburetor used several different accelerator pumps through the years. Match your old pump by measuring the cup size diameter in inches. The size will be 21/32", or 3/4". The overall length of the pump will also be needed. Use a caliper to measure this because the measurements must be in decimal. Each of our accelerator pumps will have one photo which illustrates the measurements.
We have tested our accelerator pumps with 10% ethanol gas without any additives applied and found them resistant.
