I think this is related to the fuel smell that I had noticed a short while back (which I hadn't noticed since then, so that's kind of odd), but the other day I saw sings of fuel getting past my filler cap and out underneath the fuel door on my 62. I checked the cap and it still has a good gasket and nice tight fit, but yesterday when I went to fill up, my tank was so highly pressurized that the damn cap nearly shot out of my hand when I removed it. Could this be a sign of a problem with that black manifold behind the cargo panel, or something to do with the charcoal canister? And whichever it is, is there an easy fix for it?
