in a UNIFLOW tank there are three lines one to carb, and other to muffler pressure fitting which both have clunks and the third is a vent....

in most of glow planes i run a 3 line tank 2 clunks one to carb, and fueler line wich is plugged after i fuel, and the vent goes to the muffler


could i use a T fitting to fuel uniflow tank from the carb clunk and cap the vent when im done fueling?
