WALBRO PRIMER BULB ASSY SNAP IN TYPE ETHANOL RESISTANT
Genuine Walbro Ethanol and UV Resistant 188-570-1 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. EthanolE10, a fuel mixture of 10% ethanol and 90% petrol, is commonly found at petrolstations. The ethanol found inside of fuel blends pose problems as the engines areunable to compensate for the increased heat levels, decreased lubrication andincreased corrosive effects associated with a higher alcohol content. Theundesirable result could be engine damage. Water also becomes an issue with ethanolblends. The fuel mixtures naturally hold 0.5% water in suspension, but any increasein this percentage causes “phase separation”, whereby the water/ethanol mixfalls out of its suspension and descends to the bottom of the fuel tank. It’strue that all gasoline is susceptible to the ill-effects of changes in weather andmoisture content, but ethanol makes the problem even worse. Continued phaseseparation negatively impacts fuel systems and damages engine parts, especially airpurge bulbs. However, an ethanol-resistant air purge bulb can mitigate the harmfuleffects of ethanol to drive better engine performance and longevity. Safeguard theperformance of your small engine equipment and extend its life by switching toWalbro’s new ethanol compliant purge bulbs.

Wonderful service getting this coil from halfway around the world was amazing. I think it was the last one in existence. Saved us from having to replace the engine.
