Fuel smell coming in in the inside.
 

..although not all the time and there is no smell from the rear (where the fuel tank is). No smel/drips from under the car.

It seems like it is coming from under the engine compartment and flowing in through the drive side vents, especially when A/c is turned on.

I was told some time back that the engine valve gasket is leaking, but would it cause this smell. or could it be fuel injectors? I dont see obvious leaking. May be should publish a picture.

Have you been in the habit of milking the gas tank when you fill it?

I ask because doing so over a long period of time will eventually cause parts of the EVAP system to fail; one common symptom of an EVAP failure is the smell of fuel in the car.

No (Milking).. Also, the smell does not come from under the car near the canister. it is almost like coming from under the hood.

Fuel line leak? up somewhere around the engine?

What's "milking the gas tank?" Does that simply mean "over-filling?"

Yup; it means stop filling after the first click, no exceptions. :)

Was there any work done on the car right before this started happening?

Nope. This has been happening for some time now, although as I have posted on other threads I changed the fuel tank recently but don't get any smell there.

Nor do I get smell in the rear seats. Only get it from the front and especially on the driver side when I get close to the vents on the left

Is this the 1998 Accord you mention in other threads? It always helps to know what we're talking about.

All the air vents, even on the left side of the dashboard, feed air from the ventilation inlets which are under the windshield cowling. So the smell doesn't have to come from any particular side of the engine compartment.

The fuel supply line has a fitting on the firewall, & a hose from there to the fuel rail. Look for leaks because that's higher pressure.

Fuel might leak out where each injector pokes into the fuel rail. That's an O-ring seal at each injector.

The fuel return hose (attached to the FPR at the other end of the fuel rail) is lower pressure, but that's another place to look for leaks. If there's any restriction in the fuel return hose (say you crimped the tubing while changing the tank), then the return hose in the engine compartment is operating at a higher pressure than it's supposed to be.
