Do as search here on the list for posts by Jim Thomerson. Maybe he will see this and chime in, but Jim has described and maybe posted drawings for a chicken hopper type set up where the inboard larger tank feeds a smaller outboard tank. As far as a "Texas style" name, I think it was Frank Williams (I'm not really sure) of the Texas gang that published a Bearcat profile with the engine and tank mounted on the inboard side and I think it was in Model Aviation. Custom Models was a Texas company and put out a few kits of some profiles, the Forerunner being one, that depicted the engine and tank installed this way. There should be quite a bit on the list here.
Type at you later,
