The fuel tank on your chainsaw is a plastic reservoir that stores fuel. There are several places on the fuel tank that can cause leaks, such as the grommet, the gasket, or the fuel cap. Drain the tank of fuel before removing the fuel lines and the tank itself.
Look for the oil relief valve in the side of the engine housing, between the oil outlet port and the guide bar studs. Turn up the Stihl chainsaw oiler adjustment counterclockwise to increase the oil. There won’t be any drops at all for a Stihl chainsaw bar oil clogged passageway.
If it’s the tank vent, that might motivate me to hook up an exterior fuel tank which I’ve been thinking about anyway. Might just be leaking where the fuel line goes in the tank. To access the tank ventfuel line, you have to remove the fuel tank.

What is a float needle valve?
A true needle valve uses a tapered needle in a tapered seat, so as to provide fine control over flow rate. The float valve uses a pointed needle against a square-edged seat, to give a positive shut-off. As the float relies on gravity, the chamber must be mounted vertically.
Can a leaking gas tank explode?
