1. It doesn't need thread tape.
2. The leak issue you have is very common. Basically, you have over tightened it. I don't remember what the torque specs are for that piece, but they approximate to "snugged up."
What happens is that when you over tighten the flared fitting, a/k/a the "little nut," it loosens the "big nut" on the carburetor fitting where it attaches. If you back off the little nut, you should be able to snug up the big nut. Then snug up the little nut, but don't over tighten it. This will likely fix your leak.
The big nut/little nut thing is my mechanic trying to explain this to me over the phone.
Here's a picture. I think this is what he meant.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
