I got all my plumbing supplies for my biodiesel reactor from www.plumbingfittingsdirect.com. Their prices were a LOT better than any place I looked. Black pipe included. And I needed 3/4 in pipe, fittings, etc. Shipping was cheap too.
I haven't looked for online suppliers. This is where the hardware store is your friend ... Black pipe is an extremely common building material ... Most (if not all) stores will custom cut and thread for you ...
Why not use CSST. AKA yellow flexible gas line used in newer homes.
It's not very useful for the manifold and rather expensive.
