188-566-1 Genuine Walbro Ethanol and UV Resistant 188-566-1 Primer Bulb 16.5mm Diameter


Walbro's new Ethanol and UV resistant primer bulbs have been specifically developed for use with higher ethanol blends and to protect against phase separation in fuel.
Made with proprietary materials designed to remediate the problems caused by direct sunlight and aggressive fuel additives commonly found in today's fuels.
Ethanol E10, a fuel mixture of 10% ethanol and 90% petrol, is commonly found at petrol stations. The ethanol found inside of fuel blends pose problems as the engines are unable to compensate for the increased heat levels, decreased
lubrication, and increased corrosive effects associated with a higher alcohol content. The undesirable result could be engine damage. Water also becomes an issue with ethanol blends. The fuel mixtures naturally hold 0.5% water in suspension, but any increase in this percentage causes “phase separation", whereby the water/ethanol mix falls out of its suspension and descends to the bottom of the fuel tank. It’s true that all gasoline is susceptible to the ill-effects of changes in weather and moisture content, but ethanol makes the problem even worse. Continued phase separation negatively impacts fuel systems and damages engine parts, especially air purge bulbs. However, an ethanol-resistant air purge bulb can mitigate the harmful effects of ethanol to drive better engine performance and longevity. Safeguard the performance of your small engine equipment and extend its life by switching to Walbro’s new ethanol compliant purge bulbs.
