Here is a pict., I guess I did use white tape....no leaks yet.
I forget what soider I used, but it sealed it's own soider weld mud-job. Used regular torch in hand-held bottel. One important factor to preventing a fuel leak as my IH 71 is to make sure the tank is strapped properly and that the saddel cussion is square, and not to over tighten. I used lamp oil wick from a hurricane lamp. Dont over tighten to tannk nipple.
