CK31: Made in USA. Ethanol compatible.
Complete rebuild kit for 1963-up applications with pump with round stem. Older carbs use flat stem pumps: kit CK10.
This kit contains the complete pump assembly. Most other kits on the market only have the pump cup. Unfortunately, the pumps are often damaged or have been replaced with aftermarket, non-rebuildable pumps. Our kit with a complete pump is a must in these cases.
