I want to plumb the IBS into the centre bag and use overboard pumps for the rear bags, looks like I might end up with two pumps soon.

For plumbing the center and IBS into the same system, if I T off the the front of the centre bag into the front of the IBS to fill and put two returns on the IBS legs to T off into the drain of the center bag, how do I vent them? I'm not even sure if the center bag is vented, that is how little time I've had with the boat since I've owned it. Thanks again to anyone willing to answer these questions.
