Thanks Buck. I took pix of nearly every stage,and completed both tanks[the tail holds gas too],but didn`t like the final capacity [1.3gal each],but they both came out airtight and fit good,so it will make a good template for the larger tank I started a couple days ago.I want 2-1/2 to 3 up front for weight distribution.When I get one to my liking,I`ll put up a new thread. BTW,the pictured tank isn`t going to waste,a friend of my brother is buying it to run on a small displacement SaltFlats bike.I`ll believe it when I see it.
