Aaron, there is a hard plastic line under the outer rubber covering. You can't fix it. About the only thing you can do is replace the whole line. Sometimes the barbed fitting on the connector it's self will fracture and leak. Again, the best thing to do is replace the whole line.

When the car is idling (I haven't tried taking it out with a gas leak) there is gas leaking from the coldstart valve. Any ideas? >>
