RE: Fuel Tank Frustration
Something I haven’t seen mentioned above anywhere but maybe I missed it. Before you even think about bending brass tubing heat it in a clean flame until you see it change color. This is annealing the brass tube and when it cools down you'll find it bends like soft aluminum in your fingers. No need for benders, nylon, nothing.
Without annealing it’ll tend to kink.
Try it, you’ll like it. It doesn't tke a lot of heat.
Cheers
