Stihl 036 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.

More than likely just a fuel line, you'll just have to take a minute and see for sure.

Cascaps leak aswell. Just changed it on my 036.

As above. The tank vent/gas cap/fuel line are generally the areas that leak. Fuel line would be the number one culprit.

Unless the saw took a hit, the tank suddenly leaking would be quite rare.

Appears it was the gas cap.
