Here's what you should do:
1. Safety First: Turn off the car completely and disconnect the negative battery terminal to prevent electrical sparks. Do not smoke or use any open flames near the vehicle. Ventilate the area if possible.
2. Locate the Leak: Carefully examine the fuel line to pinpoint the exact location of the leak. Is it a crack, a loose connection, or a damaged fitting? Take photos if possible.
3. Identify the Line: Try to identify which fuel line is leaking. Is it the fuel feed line (from the tank to the engine) or the return line (from the engine back to the tank)? This will help a mechanic diagnose the problem.
4. Call for Professional Help: This is not a DIY repair for most people. Fuel system repairs require specialized knowledge and tools to avoid further damage or injury. Contact a qualified mechanic or a towing service to have your car towed to a repair shop.
Possible Causes (Don't attempt to fix these yourself):
* Cracked or Damaged Fuel Line: Age, wear, and tear, or even rodent damage can cause fuel lines to crack.
* Loose or Corroded Fuel Line Connections: Clamps might be loose or corroded, leading to leaks.
* Failed Fuel Injector O-ring: While not directly a "line," a failing O-ring on a fuel injector can cause fuel leakage near the top of the engine.
* Fuel Pressure Regulator Issue: A faulty fuel pressure regulator might leak fuel.
Ignoring this leak is incredibly dangerous. Get professional help immediately. The cost of repair will be far less than the cost of a fire or serious injury.
