Use small diameter beer line so that you need shorter length.
Make the fridge cold. You'll get slower pours at 3℃ than you would at 8℃ - again you can use shorter line.
Leave the fan on and cool the lines. Less chance of foaming if temp is low and consistent.
Coil the lines at a diameter that is about the same as the top of the keg and use velcro ties to keep the coil neat. The coil will sit on top of the keg and you'll still get access to the disconnects through the middle.
If you really want, you can use velcro with adhesive backing to attach the coiled line to the ceiling or walls of the fridge, but I found the coils rested on top of keg adequate.
