Gas Tank Vent

[buddyearl]

Are these tanks vented, if so, where's the vent?

I can't quite tell from the picture, but the "knob" on top of the fill cap might be the vent.

Yep, I agree. It should unscrew (vent) counterclockwise and close clockwise

I have the same one, with no screw on the fill cap for venting.

If there are two fuel lines running to the motor, the tank is not only not vented, it's pressurized. With this setup, there is no standard fuel pump on the motor, and one of the lines pressurizes the tank to push gas to the motor through the other line.

Yep ^^^ its a pressure tank, no vent.
