I was working on my 72 Blazer some last night and kept looking at the strange stand tube thing that sits by the fuel filler in the bed. I decided rather than glancing at it and wondering what it did like I have done so many times before, I followed the lines back to the gas tank. What is this thing part of the emissions?? My 71 Jimmy has the same thing, do the 69 and 70's have this also? I am just curious more than anything about what it does...."officially".
