As I research this, the more I get confused (no doubt overthinking things again). Was looking at some info on fuel supply, lots of info on how to use corvette filter for returnless fuel system??? The 2001 ls motor I'm using has 3 feeds, actually one feed, one return, and one "vent" egr purge valve. My 95 has basically same set up. My plan for fuel system was to swap my complete sending unit with a 1996 model, which looks the same as mine but should supply the fuel requirements (I think) of the ls motor. Is my plan doable? Or do I need to research this a bit more? I do realize that my plan is going to require some modifications to the supply and return lines at the engine bay to go from tbi to ls.
