Fuel tank venting question

Well it seems that I've fallen victim to the fuel tank venting issue some others have described here. It started with the gauge reading empty on a tank I knew was > 1/2 full, and progressed to the engine quitting. Removed gas cap, got a huge "whoosh", car ran fine. Pulled the cover above the fuel pump and the tank's deformed (sucked-in) big time.
Other posts here seem to imply this is a problem with the "rollover" valve on the side of the filler neck. But I connected a hose to it and it seems to flow air easily both ways.
Does anyone know if this valve can intermittently fail?
My biggest worry is replacing the filler neck (which the valve is part of) and thinking the problem's fixed and having it recur!
Thanks,
Eric Law
