Hi,
I am concerned little bit by the fact that the air blower blows air with a hint of the gas fuel smell. Earlier I did not notice this happening, but now I can smell a slight feel of the gas when I turn on the fan of the air blower inside the car.

Please let me know what can I do to stop or avoid this issue. I am disturbed by the smell hence if possible I keep the air blower off, so that I do not have to smell the gas fuel.

 

I would start checking under the hood for a fuel leak ASAP.

 

check all your fuel lines for a leak

 

injector leak is my thought. 4 small fuel lines are an easy fix, did mine years ago. 7 bux for some high pressure hose pieces and some new clamps.

 

Hi,
The manual posted in the link has many sub sections of pdf docuemnts. I do not know which document shall I refer for checking my fuel lines. Can I get little more specific reference to look for from the Nissan maxima car documents.

Thank you

 

...

do you smell gas under your hood?

 

I had that, it was the fuel line from the fuel filter to the rail... run the car a minute when cold, shut it off, then check. My leak was not visible when the engine was warm, the fuel was evaporating..

 

I'm curious if the OP resolved this.

I just started getting a "below freezing" fuel smell from the air vent while the car is not moving. Only happens when it's below freezing outside.

 

fuel hose will expand when engine is warmed up stopping leak temporarily. I had a leak near the hose connecting to the front fuel injectors. I could immediatley detect the bad hose becuase there was residual dirty fuel on the hose (very hard to miss.) When I would wiggle it, fuel would immediatley soak the hose. To fix it I replaced my broken, worn out clamp with a new clamp and the hose no longer leaked. It is recommended to change out the hose, but I didnt feel like relieving the fuel pressure just to change out one little hose.
