I don't think it's threaded. I think it's just press-fit into the sealing material. I have used the small screwdriver to pull out the center post on my Protank. It works well!
Usually not threaded - just fitted in. Glad its worked for you.
Nope, not threaded, it's a smooth SS pin inserted into a rubber insulator. Glad you got it going though![]()
I actually realized it wasn't right after I posted. I guess just turning it slightly allowed it to be where it needed to...
