I'm no tank builder, but could you build a small arcylic box to cover/seal the drilled intake from the inside of the tank (seal with epoxy)? This would allow you to work to uncap from the exterior of the tank and work on plumbing without draining as the box will act like an airlock in between the drilled part and the water. Once complete just remove the box (maybe cut away the epoxy??)

just my 2 cents...
