When I was a student I was taught a very simple means of fuel management on Pipers. Know your endurance before you start and change tanks with fuel pump on at each FREDA check. It is excessive but you will at least burn each tank evenly.
I was taught this, but every OTHER freda check you change. Works for me, come back balanced almost every time.
It still makes me shudder when I check and aircraft and see a full tank on one side, but fuel almost dry on the other. Some student has done the QXC and not been changing tanks.
