    First it was my 385 leaking out the fuel tank vent. I replaced the white tube part tha goes into the tank. The new one didnt fit tight and still leaked. So I put 2 small Orings on the tube and put it back into the tank. No more leaks. But It went from one saw to another. Now my 346 NE is leaking out the tank vent. My stihls havent ever leaked out the tank vent. But my older 066s have leaked from the fuel cap. Never mind me I just venting.

    I have a 272xp that I rebuilt. I wanted to change the vent, but I can't get it out. It's threaded and turns, but won't come out.

    Not to hijack the thread here but what all did you do to your 272?

    Push on vent from inside tank and turn ouside. It may push out try that first. I use long bent needle nose pliers to push em out. Same on a 50-51-55-254-257-261-262 and all that use the long black tube vent. You can replace the guts don't have to buy the whole vent.

    I had three leakers. pulled out one and replaced with new one. Still leaked. Pulled it again and put a very small amount of silicone around the area that it seats. No more leak. Did my others the same way.
    I like the o-ring idea better. Probably easier to remove if needed

    I dont know what saw you have. But on my 385 I put the Orings on the very last step headed towards the fuel tank. The o rings fit into the bore with a slight press fit. I greased them up good. The problem with most silicone is that it is not gas resistant for long. To help I put them on the long skinny part of the tube. If you put three the tube hangs out to far.
