This a a genuine OEM replacement check valve for your small engine. It is also known as a fuel tank vent. You may need to replace this part if you are noticing debris or dirty oil in the reservoir. Make sure the engine is cool before you begin this repair, and remove the wire and boot from the spark plug to prevent the engine from starting up.
This blower is quite old looked on YouTube. Removed grommet with needle nose pliers. Removed tank to install new parts. I had trouble getting return line off carb so planned to reuse it after grommet was in place. Thin was a mistake because the seated grommet compresses the holes. Took unnecessary time to get it through. With my trimmer with all lines in place. Hardest part was to get the grommet to seat even with silicone.

Echo Trimmer reconditioning and service
I purchased several parts for my 25 year old SRM 2400 Echo Trimmer. New engine cover, gas filter, breather, air filter, gas lines and seal for gas tank.
All parts arrived as ordered and fit excellent. Repairs were made easily and someone with very little skill set could do what I did, despite my mechanical ability.
I will continue to use Partselect for my needs in the future. Very good service.
