On my tank, the vent line is attached at the top of the tank, near the gravity fill hose, and does not extend into/inside the tank. The other end of that vent line is actually attached next to the cap of the gravity fill port, above the tank level.
I don't understand how this "siphon" is happening. If it is siphoning 1/4 or 1/3 of the tank volume, then that would require the vent line to be down inside the tank 1/4 or 1/3 of the way, and the loose end to be below the tank, regardless of how high the line goes (or loops) between the two. Can someone post a diagram showing how their tank lines are set up, including both the vent line and the fill line(s)?
