Car is a 2003 mercury sable GS, V6 engine.



Fuel is leaking from the top of the gas tank only when the

engine is running. With the key in the run position i can

hear the fuel pump turn on and pressurize the system

and there are no leaks. It only leaks when the engine is

running. The fuel pressure is within specs. Only 50k

miles. New fuel filter installed. Using shell regular unleaded gas.

No OBD codes when scanned. Check engine light is off.





Any idea why it only leaks when the engine is running?



I did a google search for this problem, no usefull results.
