I am anxiously awaiting a report on this project. I've been looking at mine, thinking it looks like it will just slide out, also. If it does, I'm going to pull it out and move the overflow connection from the side to the top of the tank.
Please report how the project goes!
Hey! Might be able to save you some effort... I did some more research and found that with my polyethylene tank I would have to 'spin weld' the new fitting on.
BUT!
Looks like there is no need to move it. I'm just going to alter my vent a little bit and install a siphon break...

As long as the top of the larger tube is higher than the top of the tank, it will fill, spill over into the larger pipe, but the larger pipe won't let it siphon down. And because the 1/2 tubing runs up above the top of the tank, it won't flow until the tank is full, but at the same time, the water can't run UPHILL to drain.
Hopefully this all makes sense.
Certainly a lot easier to do than to move the ports.
Let me know if you need more info!
