Product Description

Genuine OEM replacement part used on Echo chainsaws. This part keeps the fuel tank sealed and prevent gasoline from leaking. This item includes a retainer that remains in the tank to keep the fuel cap from being lost or falling on the ground. It also has an o-ring supplied with it to seal the cap. After time this o-ring will deteriorate and become brittle causing fuel to leak from the tank. It will then have to be replaced.

I replaced air and fuel filters and new spark plug. Once I completed repair saw would start but acted like it would run out of fuel. I let sit for 24 hours and then tried it and it has been running good ever since. I believe the new fuel filter takes time to become fully operational.
