Edit: Cut the pipes with circles and use Couplers to re-connect the pipes once the arrows are lined up.

I shortened it exactly like you said. Siphons great but when the water drops below the inlets inside the tank is loses siphon and I am back to square.
It's driving me nuts
your getting air in there somewhere. All of my overflows will start right back up. its best for the cost of the PVC to just start over. If I were you I would plumb them seperate also. That way you'll double your flow and have a backup. Right now your only flowing as fast as you would with a single.
that could be where your getting air, but Ive had them hanging at like a 20 deg angle and still work. Not great but ok.

I have since made a single inlet version and I am having the same problem.
I have a video in a thread a couple down of the single version.
I think it has to do with your Airline setup. A nice way to test for a leak. Cap one end submerge it in the tub and blow into the other end with a shop vac.

when the water level gets near the intake tube it sucks up air and looses syphon by filling the piping with air.. so everytime it does this you need to suck the air out of the tubes to get it working again.
there is your issue. with the airline tubing you can hook up a powerhead with the aeration tube hooked up so it sucks out the air everytime your pump primes. thats one option.
(experimental) also maybe puttin the T near the desired water level of your tank.... by this it stop the syphon once the level drops past the T...at least thats what im thininking.

bjrouse... I am the one you based your design from in my first video... It is an optical illusion when you thought i had one U piece higher than the other... Water reflection can trick you.... Both U pieces are a Mirror Image.... But when you cut your pipe to make both the same length. Make sure your output to your T is lower than the top of your input pipe.. If it's higher than your input pipe the water will not siphon.....
