Genuine Walbro Ethanol and UV Resistant 188-566-1 Primer Bulb
Walbro's new Ethanol and UV resistant primer bulbs have been specifically developedfor use with higher ethanol blends and to protect against phase separation in fuel.Made with proprietary materials designed to remediate the problems caused by directsunlight and aggressive fuel additives commonly found in today's fuels.Ethanol E10, a fuel mixture of 10% ethanol and 90% petrol, is commonly found atpetrol stations. The ethanol found inside of fuel blends pose problems as theengines are unable to compensate for the increased heat levels, decreasedlubrication, and increased corrosive effects associated with a higher alcoholcontent. The undesirable result could be engine damage. Water also becomes an issuewith ethanol blends. The fuel mixtures naturally hold 0.5% water in suspension, butany increase in this percentage causes “phase separation", whereby thewater/ethanol mix falls out of its suspension and descends to the bottom of thefuel tank. It’s true that all gasoline is susceptible to the ill-effects ofchanges in weather and moisture content, but ethanol makes the problem even worse.Continued phase separation negatively impacts fuel systems and damages engineparts, especially air purge bulbs. However, an ethanol-resistant air purge bulb canmitigate the harmful effects of ethanol to drive better engine performance andlongevity. Safeguard the performance of your small engine equipment and extend itslife by switching to Walbro’s new ethanol compliant purge bulbs.
