I was driving and I started to smell gas. I can't see a gas leak any clues

 

You say you can see a gas leak, where is it leaking?

 

I would check your fuel injectors and the small copper gas line on the left side of the manifold.

I had a similar smell in my vents and it was that little copper gas line. The rubber on the ends was cracked and leaking a small amount of gas.

 

I can't see a leak. This smell is when I got my ac on

 

I gotta smell like that too, seems to be coming through the vents but i can only smell it when the car is stationary for awhile......

 

you may want to pull the backseat and check the fuel sending unit. You have to take off the fuel pump cover, but if you look down the top may be a little wet from gas. I had this happen and noticed the gas smell when I filled up my tank. The crack was pretty high up in the unit, but whenever the tank was full it would leak a little. As the gas level went down it would go away.

 

i also have this problem but my upper intake manifold is also wet so im going to replace the gasket that should fix my problem i dont get bad mileage though about 24mpg's
