I cannot find the fuel air vent or tube. Does this saw have an air vent?
For model number Echo CS-341
Hello John, Thank you for your inquiry. Part number V471001200 is the vent tube, and the fuel tank vent- part number A356000031- allows air to re-enter the fuel tank. Hope this helps!

Fuel line grommet rotted
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.
