Thanks Derek no I ordered it from the home planet in the pacific along with some more coils/ O-rings.. looks like the drip tips o-ring themselves are sold with a new tip ?
Kind of weird but makes sense if a company would rather sell a 3.50-10.00 $ tip instead of a o-ring set for .99 cents
That might be what's wrong with the tank ?
It isn't as snug as the new one is,
FWIW I wouldn't use the drip tip as a means to fill the tank.
Just unscrew it and fill the sucker,
