Junkyard?? I have been looking as well(not that hard though), my 93 is not leaking from the neck, its leaking from the top of the tank where the neck connects...I'm guessing the seal is bad, but it could be the neck at that point and not the seal itself...But my filler neck is all rotted looking, so I need a new one of those as well. I just parked it until I can devote some time to taking the bed off and actually seeing what the problem is.
And I plan on taking the bed off to do all this...pretty simple if you have a body lift like I do though. If you have planned on body lifting your truck, this would be the time to do it.
