99 BUCKET

I have a 99 5.3 s-10 running for over a year. I have recently gone to a l92 water pump for better clearance. However, I want to make a solid upper tube for my rad hose and connect it with rubber (almost like the flex stainless ones). I want it smooth and clean. but, I CAN NOT FIND WHAT I AM LOOKING FOR!

I need 1.25 or 1.5 aluminum tubing that I can get 180 bends and j bends. I can find it any were. I can weld it but cant find the supplies.

any points in the right direction? Thanks
