Can't really see the damage but in the meantime if they don't flex try JB Weld epoxy. Clean and clean again. Work goo around area and poke into hole, open if needs be, so it mushrooms inside a bit, then a bit of light heat if it's cool there.
Block it up and test. I use a bung with a shrader valve in it and a couple of pumps from bicycle pump in bucket of water.
