Fuel Starviation part 2

I am at a loss as to the problem http: I got this jeep in April and this has happened every time to the best of memory, When my tanks get about half empty, I get starved for fuel. The problem has been complicated by vapor lock through the summer, but now, heat is not a factor. What have I done to solve? New Gas tank (went from 15 gal to 25 gal) and with the old tank, the problem occurred when about 8 gal low, and with the new tank, about 13 gal, I have also put front to back new fuel line, put in a elec fuel pump, added an un- restricted line to vent the tank (to eliminate a vacuum on the tank if there was any) , new mechanical fuel pump and new fuel filter. Reading other threads on this forum, I discovered I may have the fuel filter in wrong, and turned it where the return line was on the highest radius and the return line coming out and up in at the highest position (I really though I had it). Today, about half low, no fuel to the carb, bowl empty, filled it up (13 gals) (primed the carb) and I am good to go.
What could it be?

When you replaced the fuel tank, did you replace the float in the tank?

Question on replacing float in new tank. Yes, the new larger tank was a complete kit, and included the dip tube and float already installed (also included hardware to extend the skid plate). I examined the dip tube through the main nozzle hole by shining a light down the nozzle vent line, and could see that the dip tube ran near the bottom of the tank (was trying to see the float too, but could not get the correct angle to see it) Not that it matters, but the fuel gauge indicates near empty when I am 13 gal low (on a 25 gal tank)
