What can cause gas smell inside car?
Filter? Or more dangerous problem?

 

Purge Valve or Fuel Rail Dampener are most common.

 

If the tank's under the rear seat, the access for the pump(s).

Yes it's dangerous...

 

Under what conditions do you smell gas in the cabin?

 

The purge valve is located in the drivers side wheel well. If that's the source the recovery system is compromised, but not a serious danger from what I have read. Still, it needs to be repaired.

 

Gas is very smelly, so you should be able to track the source of it. Take the engine cosmetic cover off and look around. Folks have had leaks at the dampeners on the fuel rail. I have experienced a leaky fuel pressure sensor, right at the end of the rail. Temperature permitting, check for wet spots around the rail and use the smell as a guide. And yes, this has the potential to be a big safety risk. Carry a fire extinguisher around until this is resolved.

Best of luck, keep us posted.

 

Imo, if you are not comfortable with it, take it in for service.

I changed my purge valve but wouldn’t touch anything else fuel related. Risk/reward.

 

 

Do you top off when you fill the tank (don’t)?

 

 

Plus one on this.... had that happened on me...it was the purge valve inside the wheel well of the passenger side. It could also be the charcoal canister underneath the vehicle by the trunk.
