| Description: | Genuine Walbro Ethanol and UV Resistant 188-566-1 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. |
