A 3 line tank is the answer, (not Uniflow)
You will find that a 3 line tank is easier to use and maybe will become a stock set up in your next build.
There several variants when using a 3 line set up but go simple and use only one line directed to the carb, a second line to the muffler pressure and a third line just for refueling, do not forget to plug this line after refueling.
