    '91 4Runner with the 3.0.
    Gas is leaking from the charcoal filter down into the hose that empties into the frame. Can I cap off any of the lines going to or the one that drains into the frame to keep it from leaking?
    I put a new gas cap on it and it did not slow it down....Slowed it down when I leave the gas cap loose.
    Thanks in advance.

    Thanks. I will replace the canister. Used to work on all my vehicles. 35 years of diabetes has stopped that.

    Why is there gas dripping from your charcoal canister? They only deal with vapors. I would look and see why you have a fuel leak. Otherwise, you'll just saturate a new canister.

    You are correct, the canister is only getting fuel vapors from the tank. If the canister does not purge the fuel vapors, eventually the charcoal gets saturated. When that happens, the fuel will condense out of the charcoal and drip out of the bottom of the canister.
