Original Walbro Ethanol Pump ball ZN0069/01

Since 2019, bioethanol has been added to the 95 and 98 octane fuel. In E10 petrol this is 10%, in E5 it is 5%. When using these gasolines, the ethanol can cause damage to, among other things, gasoline pipes and other rubber parts, such as the carburettor.

Walbro has developed this new ethanol- and UV-resistant pump ball especially for use with these gasolines. Made with proprietary materials designed to overcome the problems caused by direct sunlight and harsh fuel additives such as ethanol.

This can be easily exchanged with the existing pump ball of almost all Walbro carburetors.

Suitable for instance:

• Walbro WT603
• Walbro WT603BB
• Walbro WT668
• Walbro WT668BB
• Walbro WT990
• Walbro WT990BB
• Walbro WT997
• Walbro WT997BB
• Walbro WT1107
• Walbro WT1107BB

We also recommend replacing the rubber diaphragm with the KW-WYTA tuning version
