    Fuel smell coming from the trunk

    I decided to dig into my fuel smell problem. I thought it was coming from under the hood. The injectors don't leak. I had this problem when the stock injectors were in it and I have this problem after the new injectors and o rings went it. There isn't any leaks anywhere. No wet lines, no puddles on the ground, not even any dried fuel stains on the tank. I started looking into the charcoal canister. I've read they can fill with fuel. No problems there. I then started checking the lines to and from the can. Other than being a little old they didn't have any problems.

    Blowing into the line from the charcoal canister to the tank I heard a hissing sound. I followed this sound all the way back to where the line hooks up to the tank. It connects to it on the very top, where you can't reach, and not the sending unit. If the tank was sealed it wouldn't hiss. Am I right in this assumption? It also doesn't hold any pressure or vacuum.

    Are these tanks prone to rotting out at the top? The rest of the tank seems very solid. I sure don't want to drop the tank on this almost 20 year old beast.

        I agree, also check the canister. I had the same problem, the line was plugged up. The vapors got so bad, it was making me sick. Even when the car was just sitting in the driveway.

          You can reach and see the top of the fuel tank if you jack the car up and let the rear axle droop. Look across the top of the tire and you can see the two plastic fuel lines and the rubber vapor tube. If you can see with your fingers, you can replace it without dropping the tank. Be sure you have the car well supported on jackstands if you do this.
