Gas smell
I have a 21006 F150 5.4L. I can smell gas in the cab when outside air is coming in through the HVAC system. I can also smell gas under the hood when the engine is idling. It is not constant, it will smell for a minute or so, then go away for a minute or so. Any ideas what may cause this?

Could be running too rich due to the follwoing below:
1.Excessive fuel pressure can be cause by restricted fuel return line
2.Defective Oxygen Sensors.
3.Leaking injectors and fuel pressure regulator.
4.Coolant temperature sensor out of calibration.
5.Restricted air intake system.
6.Leak in the Evap system

Thanks for the info. I do not have any warning lights on. Do I need to go to a Ford dealer to have it checked? Or do you think a private mechanic could determine the problem?

An independant reputable shop can do it-cheaper
