The past few days I have been smelling what seems to be fuel every time I turn on the heater. It is very pronounced when I turn on the fan (usually on setting 1 or 2), open the vents to let the cool air outside in, and when I am at a complete stop. My guess is that the fan is funneling the scent of fuel inside the cabin. Once while driving, I shut off the fan but left the vent open and the smell seemed to go away.

My question is, could this be a sign of a possible fuel leak? I have been checking underneath the car and I don't notice any fuel leaking. My fuel gauge looks normal and my gas mileage is about the same. Or could it be that I'm running rich? I don't have an A/F controller so I really have no way of checking unless I take it to a dealer or a shop. Or is it nothing to worry about?

Any help would be appreciated.

Here are my engine mods (if it helps)
'02 WRX
APS SR30 Turbo
APS Dual Entry TMIC
APS BOV
APS CAI
APS Turbo Back Exhaust
Unichip

Thanks guys

Thanks for the response! Would this be something that is covered by the dealer? The reason is that I have only had the car for a month and a half so This should be taken care of with the warranty I have.

I'm going to search for that post. Thanks!!

After searching here and NASIOC I found some really good articles on the problem including that one. I'm going to take the car to the dealer and see if they will fix it.
