Echo 2511 fuel tank pressure

[lux]

Anyone else have a 2511 that seeps a little fuel from what I assume is a breather. Only occurs on full / nearly full tank so assume it's pressure related.

When you do the cap up, the air the cap traps when done up compresses the fluid in the tank, same on every tank. If the breather fitted is two way, it will leak a little. I don't know too much about this machine or the breather fitted though.

Appreciate an old and very short thread…. Did any of you guys have any advances on this? I have the same issue my saw has been running years and this is only just cropped up.

You can check for leakage by plugging the breather and purge lines then pumping air in through the fuel line with a Mityvac.
