Terry, most of the current fuels already have anti foaming agents.
I've never wrapped my tanks and foaming isn't an issue. I fly four strokes, 52 thourht 91 sizes, so there is a lot of thumping of the air frame.
As others have pinted out, start at the clunk and work forward. I will just replace all of the lines and make sure the brass tubing is OK. If you go throug the effort of pulling the thank, it is eaiser to eliminat everyting at once vs three or four trips in. It also saves wear and tear on the plug.

I second that Don.
Most Arfs it is hard to wrap a tank with foam... there just isn't any room! If you can wrap a tank with bubble wrap or foam, it will take out some of the vibration that can cause the foaming effect in your fuel line... especially if your prop is not balanced.
Have a well balanced prop, and you won't have much of a problem. I don't wrap my tank either most of the time.
