The Aeromotive system is called Stealth. I looked it up after seeing their ads on either Gearz or the NHRA ProMod Series on TV. It fits in a stock looking pump opening in the tank but still uses -AN fittings. They may be in the tank and more easily converted to stock steel, though.
EDIT: That tank is very similar to the Fox body Stealth tank from Aeromotive and probably will take the same pump. Check the specs in this link:

The Ebay seller isn't Aeromotive. Different area code. Might be a Chinese knockoff.
