Your copper lines remind me of the coolest 'FUEL' lines I've ever seen, done in same stuff just smaller, maybe 1/4 or 5/16"? This guy had six carbs on a V8, the fuel lines were built from copper with fittings as you have done, then CHROMED, WOW a work of art. No bulky fittings to deal with, very simple, and neat as a pin.
Kudos for your originality and craftsmanship.

P.S. I saw one of these intakes with the return line 'T'd into the hole for the temp sender, just food for thought.
