Default Fuel Tank Help

I just finished my Uproar and was at the field getting ready to test fly it(I didn't since it started raining[&o]), but I noticed when I tip the plane forward(nose down) or when turned inverted fuel runs into the vent line and into the muffler. I have never had this happen on any of my other planes(at least I never noticed). I have the same setup as my other planes with just a simple bend up of the vent tubing in the tank, and the tank is at the same height as the needle. My question is, once the motor is running will the pressure prevent this from happening? Has anyone seen this before??

It's very typical. Put the fuel level above the vent, and... well, the fuel is going to follow the laws of gravity.

Once the engine is running and that vent is sucking air, it won't happen.
