Leaking fuel at evaporative canister

[Rup]

All of the above comments about the canister are good and should be checked. There is another possibility; it was never said weither the vehicle was carburated or fuel injected. On the outside chance that it’s fuel injected,. most high pressure and electric fuel pumps have a return line that goes back to the tank. One function of this line is to keep from overpressurizing the fuel injection system. If the return line came loose or is split, broken or blocked; this would also account for a fuel leak at idle or low speed. I’m trying to think outside the box a bit. When troubleshooting you start with the most likely and work to the least likely until you find the problem. Good luck with this one.
