I am in the process of building a Phoenix Tucano. The fuel tank I'm using is a 3 line tank and I have a Dubro fuel filling system which suggests putting a second clunk on the filling line so that you can use that to empty the tank. Both clunks are metal so would this cause interference with them banging into each other in flight or would it be fine?

thanks

You should be fine. I've never noticed any interference when using two clunks.

No, they won't cause any interference. You'll be just fine with that setup.

Thanks for that
