I read 9/16 where it actually said 7/16 when drilling the hole in the inboard tank rib for the AN833-4D bulkhead ell. The oversized hole is big enough for the ell to slip through the hole entirely.
My intuition is to proseal and rivet a ~two inch round patch over the hole on the inside of the tank then drill the center of the patch to the proper size, but I'd appreciate confirmation that this is the appropriate course of action.
I could also just patch the oversized hole and relocate the vent line, but I don't know what consequences that will have later in the project. (This is a 7A; the plans say "locate approximately" when discussing the hole in the first place.)
Thank you for your help
