Had a very weird experience with a seemingly one-time fuel leak. On a cold morning yesterday when the vehicle was started, a very strong fuel smell was evident and fuel was dripping from under the engine. Shut it off. could not visually see the source. Tried again later in the day and problem did not repeat itself- no visible leaking under vehicle. Then tried it again this morning, equally cold, and engine started and ran with no fuel leaking. Anyone have any ideas on the cause? Possibly a dose of water in the fuel from condensation in the tank that got into the line and froze causing a blockage? Any Ideas? Fuel filter was checked and was dry right after the leak occurred.
