I understand draining the tank if you have contaminated fuel, but there is no need to drain the tank to fix anything we have discussed in this thread. The on deck tank would at least eliminate the boats fuel system as a possible issue. You can pull the pick up tube without draining the tank. The pickup is where you'll find the anti-siphon valve and the possible sock filter.
