remotely located fuel pump

First off, yes, I tried using the "Search" feature to no avail.

I recently saw a post on a Mikuni fuel pump for a bike that had the gas tank under the bottom frame rail but I can't find it.

I want to put the gas tank on my stretch cruiser behind/below the seat tube.

Any help would be appreciated.

Thanks, my tank is gonna be as low as possible-that's my concern. I'm not too concerned about cost. I need it to work.
