The stainless tank that I ordered from
Rick's Hot Rod Shop arrived today. It's narrowed for the mini-tubs, has integrated sump and baffling for EFI, has a -10 pick up and -8 return, a GM 90 ohm sending unit, and is slightly deeper to make up for being narrowed. It should be right at 16 gallons.
It looks fantastic, the craftsmanship is first rate.

Thanks again to all the guys at Rick's.
