it's kind of silly, but sorta overlooked.
I have a 90 degree elbow that feeds thru the bulkhead to the dart.
I simply turn it upside down and attached another tube that goes above the water level and voila! I've tried it a few times and it works. Of course putting a valve before the dart woulda been the smart thing, but I have space concerns and it would have been too tight.
