This looks good! I have a similar cooler that has the exit a good inch above the bottom of the cooler. Using a SS Braid I have about 1.2g of deadspace. I'm needing to come up with an idea to get a siphon to run to have less dead space, or make a manifold similar to this one.
Thanks for the great documentation!
