Wayne,
I sent him a simple drawing of a 8" round aluminum tank, 16" tall with two 1/4" NPT bungs welded in the bottom.  If you look in the picture you will see how I positioned the bungs.  I also had him put a vented cap on top.  I picked this size as it fit in the same clamping system used by the plastic tank.  The only change was I had to use a little longer bolts on the clamps.

You might send him a picture of mine along with a drawing.

I hope this answers your question........................................

It does. I ordered the tank, today. Should be here in 8-10 Days.
Thank you for your information.
