Arrow Sac Plumbing Question

[cwindingland]

For those who have plumbed an arrow sac in their boat, which ports did you use to fill and vent? Seems obvious to fill from the bottom port but questioning which one to use as the vent. I would tend to think the ports up on the arrow part of the bag might allow the bag to fill a bit more but maybe it doesn't make much difference.

Also, since the fill/drain port on the arrow sac will sit lower than the overflow on the hard tank, should I would expect there to always be some water left in the bag. This is different than the piggybacks in the back where the bag sits higher than the hard tanks and gravity is on your side.

Your thoughts and insight are greatly appreciated.

You are right. I used the low rear as the fill port, and the arrowhead point for the overflow.
