Inline tube distribution block question

I just used the factory distribution block in my 1964 and 1965 Mopars when converting to a dual MC. Since the top port was 1/4", I screwed an adapter to 3/16" inv flare for the new front tube from the MC. I ran the new rear tube from the MC around the distribution block, using an inline 3/16" inv flare coupler to the factory tube going aft. I plugged the rear port in the distribution block. I bought all in bubble packs at Autozone.

My guess is the Inline Tubes rear ports are independent of the front circuit, so just serve as a coupler. It would be nice if their block had an "imbalance warning switch", as in say a 1969 Mopar drum-drum block, since that is the main reason to plumb both front and rear circuits to the same block.
