So I bought the coffee urn type of dispenser for this and it was the wrong size. The 9" output is all 1/2" tubing size, and I bought the 3/4" coupler with the coffee urn adapter. I'll need to return it.
What worked for me instead was to pull a silicon funnel over the draw off elbow which reduced the output size to something I could fit inside the bottle opening. It stayed put through 7L of hot syrup and I'm very happy with the improvement. No more syrup down the sides of the bottles.
Funnels like these... I used the green one.
