Is the fuel tank vented at the fill cap? Two partial holes in the factory cap but doesn't seem to be an opening. There is a "surge plug" on the back side of the cap. INCA 33 gallon tank. Trying to track down possible fuel delivery problem. If not vented at the cap, I can't find it without taking out storage boxes or the tank itself.

Also, how does one remove the anti-siphon valve? Looks like one has to have access to the inside of the tank? I have the 45 degree type. There is a round threaded nut at the base of the fitting securing it to the tank. Is it threaded into the tank? Or is there a nut on the other side that will fall out when you unscrew it? In all the other posts I have read regarding the anti-siphon valve nowhere could I find how the thing comes out. I just would like to avoid a nut falling into the tank from the back side if there is one. Any info appreciated.

Thanks very very very very much in advance.
