I have 2 of the built in predrilled overflows in my 180gal tank, but I would imagine the concept is quite similar with the hang on tank overflows.

A word of warning if you try the vinyl hoses, and that is it is stored coiled and large diameter tubing doesn't like being forced to bend the opposite way that it was coiled. It tends to kink. I installed it as single piece of hose bent into almost an S shape from my main tank to my sump. It kinked up on me so I cut out the kinks and inserted rigid plastic 90° elbows in their place, which prevented the hose from being obstructed and reducing the flow.
