71 Duster Fuel vent

Ok! Wow. Thank you both! Looks to me like I'm going to do the 1969 model I'll just have to figure out how to get a nipple onto my filler tube. I don't have that strange can in the front of my car and it's not a numbers car. So the cleanest, easiest, down and dirty approach. Man, you guys are great. THANK YOU!
