Next question if I may; wing leading edge tank (infront of main spar),
Wing chord tanks (behind main spar) or wing tip tanks? Considering that I
am wanting to make the main wing foldable (fold up then sideways aft) for
trailer storage & transport; which would be the better option and how to
ensure the piping etc will work with folding wings?

You ARE looking for a challenge. That complicates things considerably.
Without considering folding wings I'd say keep the tanks as close to the
main spar as possible for CG considerations and tip would be my last
choice as weight out that far on the wing could affect handling in both
roll and yaw. Folding wings on a KR puts you rather far in to the weeds
as far as engineering goes. Seldom if ever done. I think one gentleman
in England had a system to remove / install wings without assistance.
You might consider that route but with fuel in tanks that becomes more
complicated also. You may have to scale back your plans to keep fuel in
the cockpit and design an easily removable wing. Any chance you can find
a hangar to share?
