The fabricator is giving you good advice. While foaming in was the best practice, it is not anymore.
One benefit to foaming in is keeping the tank secure. If you are overly concerned the tank is not secure with the OEM straps, you can either foam just the corners or use strips of composite.
Several veteran members have mounted bilge hose (with a screen on the end) to the rear wall of the cavity and then ran it aft. It was connected to a manual pump when desired.
