Brand new, factory sealed.

If your saw’s vent is clogged or the cap’s leaking pressure, this is the fix.
Keeps fuel where it belongs and air moving the right way.

Small part, big job.

Don’t rig it—replace it.

Made for the models listed, so check yours before ordering.

Solid, simple, Stihl quality.
