Stihl 036 Pro gas Leak

[sundance]

One of my 036's suddenly has a gas leak. I haven't had time to try to pinpoint where as yet. Any common leakage sites I should be looking at?
Looks like the tank is part of a handle assembly if that's the issue. How expensive are those? Hard to replace?
Thanks for any ideas.

The tank assembly is pretty cheap to replace. Some common areas for it to leak are the gas tank vent and fuel line most likely around the grommet area where it connects to the tank. It could also be the gas cap but that isnt to likely but it can happen and a crack in the tank would also leak but that wouldnt happen unless the tank was very old and rotten or you dropped it really hard. The fuel line, gas cap and gas tank vent are all easy and cheap to replace. Goodluck

Appears it was the gas cap. Replaced it, no leakage so far.

That's a common problem. You found it before I got a chance to reply. Likely the fuel cap was either cracked or had a bad washer seal. Good luck!

No cracks......must have been a bad seal. $6 later it's back to work.

BTW, the seal washer is available as a standard repair part.

Never thought of that. Guess I should have kept the old cap.
