Hi Rick
I purchased a set of stainless tanks from Hall Pantera.
I removed the neck from the swirl tank and fabricated a round "blank" to fill the hole where the neck had been.
I acquired stainless AN style male fittings. As best I can remember I purchased them via McMaster-Carr. Then I drilled holes in the tanks where I planned for installation of the fittings.
Then I had a local welder do the welding for me, he welded both the fittings and the "blank".
The hoses and associated AN fittings were acquired via eBay.
The tanks were painted black to look "OEM". Bling is not my thing.
