I was looking at a Tanks Inc one, but they are not out yet. I like the separate sender unit from the pump.
On the Spectra tank, the pump and sender are combined and it was a pain to remove it from the tank. Only reason I removed it was to see what pump was used and how it was baffled. I forgot to take pictures, but it looked decent, so I will just install it and try it out. I'll post updates after installing the tank.

One thing with the spectra setup, the pressure and return lines are 3/8" supply, 5/15" return, and they are the regular style where you push a fuel hose over the connector and tighten it with a hose clamp. I guess it will be OK with the higher fuel pressures? I'll find out.
I did buy hose to -6 AN adaptors so I will just use a short length of EFI barricade (Gates) fuel line from the tank to the adaptor, than connect my existing -6 AN fuel lines.
