Integrated Bow Sac install

Thanks for the link on adding the vent, looks very simple.

Also just so I'm clear, use a Y fitting from the new vent/fill line from center sac to drain on each leg of the IBS and that eliminates the need for the additional through hull drain and pump all together?

I would split the line right at your current vent/thru hull. Then hook in one side to the center sac and one to the bow sac. I ended up installing a new vent for the ibs as its really and easy job
