Drill a 10mm hole, stuff around for two hours trying to get the nut on the inside to screw to the pet cock from the outside and your laughing.
Obviously, if you choose this route, you will need to position the pet cock as close to the filler as possible.
Sounds fiddly but also a great idea. I’ve done a search and found several that may be what you are describing. Would you mind posting a pic of an example……Thanks again guys!
Like this.....just add a nut on the inside?
