Agree, relocating the tank is a relatively simple project. See posts #1162 and 1166.
I was using an OS 1.20 4C with a Perry Oscillating pump and it ran better than ever with no in-flight leaning. I remember having such a problem on outside looping segments.
Having the tank on CG also makes problems (leaks, tank clunk/plumbing) easier to spot and provides much easier access for repair.
