Having eventually mastered the various 'snap-on' fuel line fittings from the VZ donor I'm using I've come up against another GM fitting for the charcoal canister. Is looks like a snap-on but I wonder if it's a snap-off as well? I've tried the techniques for the the other fittings but no joy.
Anyone know how these come off or if they are supposed to be tamper proof? It's certainly Idiot proof!
