Fuel Line Flaring Kit?

HF one...take the 2 halves of the fixture and run them over a piece of sandpaper, get them nice and flat and even take a thou off, then use them chucked in a vice! The little screws never got mine tight enough for me. Also dont try it on OEM metal brake line. It will bugger up the cone. The newer softer brake lines are OK. Dont know why they made the press cone out of low grade metal but you could turn one in a lathe if your equipped.
