Stock tank with efi flange?

I used an aeromotive stealth 340 on my stock tank. Install is very easy and it works great.

$500 is a little out of my budget. I like the simplicity though, something to keep in mind when I design mine. Scary running power into a gas tank......but its been done millions of times now.
