WALBRO PRIMER BULB ASSY SNAP IN TYPE ETHANOL RESISTANT

Description: Genuine Walbro Ethanol and UV Resistant 188-570-1 Primer Bulb

Editorial: 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.
