Gas Cap/Filler Neck

[bpope]

Ok, thanks for the help guys! Jimmy, yes - the tank is moved to the bed - it's just a keg that is used as a gas tank. Kind of cool, but not really my style, so I will be moving it under the bed at some point. I will probably have to get something made since most of my airride stuff keeps me from running a stock under the bed one. Regarding how it was filled in, I looked on the inside of the cab and it appears that the rolled lip is still there. I will snap a pic of that.
