Have a raw gas smell inside the cab, any ideas on what could be causing this. When heater is on and vent at mid section I notice the smell coming in worse.

 

I have the same problem on my 2010 f-150 SCAB. Have to run it recirculating all the time. Would like to know the cause. I have the 4.6L engine.

 

Someone on here hopefully will have an answer as to what it could be. Almost appears to be a similar issue they had a few years back, when the spark plug would blow out of the head, and gas squirting from that port. I heard of a few vehicles that burned up because of that.

This new issue could cause an explosion, with the gas fumes present.

 

Are either of you filling your tanks beyond the first click or first shut off at the pump? If so, you're overfilling your gas tank.

 

Possible cause is injector seals, have seen this before especially on colder days..

 

Thanks for the reply re injector seals, quite possibly could be. Still does this not cause question for safety. With gas fumes hanging around the engine compartment, could very well cause an explosion. Imagine going down the freeway and your hood blows up in your field of vision.
