Wish I'd known this before. The tubing comes in a roll. I unroll it and cut it to length but it is all wavey. Solution is to straighten it roughly by hand and then use a 2x4 or board to roll the tubing over a flat surface. The result is as straight as you can get it without special tools.
Made the fuel line from the right tank to the fuel pump area. I am going to use a different fuel valve and the fuel injected engine so I ordered all that from Van's so I can finish the fuel lines before I rivet the front skins.
