I have options to *run a connection pipe from the upper barrel (A) *to

1. Connect from top of barrel A to top of barrel B
2. Connect from top of barrel A to bottom of barrel B
3. Connect from bottom of barrel A to top of barrel B
4. Connect from bottom of barrel A to bottom of barrel B

Which would be the best option? Or maybe there are other options that I
not thought of?

Thanks for replies in advance.

Obviously a new barrel is designed to hold most things it may be
required to hold. Sometimes with another barrel on top. None are
designed to hold 2 barrel load-fulls.

Nor are the taps, seals and etc.

Can you raise the 2nd barrel with a dais or something so both fill and
empty simultaneously. It's a fecking garden, don't waste time
wondering about potability.

When it's dry weather take "B" off the dais and fix pipes bottom to
bottom. You can just join the taps. Put a couple of stones in the
bottom of "A" near the exit to help filter. I presume it's too late to
raise the position of the tap of "A".
