Re: i can smell the fuel fumes inside the car when...
My experience with this particular issue leads me to believe that you probably have a rusted fuel line or lines at the top of the fuel tank, assuming that the fuel lines are OK under the vehicle. This is a very common problem. There is a bracket there that holds the fuel pump inside the tank, and the fuel lines that are welded to the top of this device are wont to develop pin-holes over time and age. Very noticable when driving, most likely the line going to the engine is the culprit. Get under the vehicle and see if there is wetness at the top of the tank. If so, you will need to drop the fuel tank and replace the fuel pump bracket. I hope that this helps you solve your problem.

Do not top off your gas tank. The gas is going into carbon canister which is only for fuel vapors to go into (carbon canister opening near the top of fuel neck near the gas cap). Your flooding the fuel vapor canister with liquid fuel; of course you are going to get a sensor message...
'Evap emmission,control sys leak
P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned again...it's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)
This is a somewhat common problem on Nissan products. The V6 engine has several small rubber hoses connecting the fuel lines, and when it is cold weather the hoses leak fuel. The heater - defroster picks up the fumes from the outside vent under the windshield. When you are moving the fumes flow under the van. If you can find the leak sometimes you can just tighten up a clamp or two.
I've had this problem on a 924 and a 944. The problem will be the seal around the rear tail light, on the exhaust tail pipe side. Another source of the problem could be rear hatch seal or rear hatch adjustment.
If you smell fuel too (with a full tank), replace the hose and the two rubber sleeves between the fill point and the fuel tank. These are under the carpet in the rear of the car.
Hello, This could be dangerous to you and your family here. There could be a
number of reason it sell like fuel in the car/truck. All vehicles are a close
operating system on the fuel circuit, that means no leaks or leaky fumes of
Don't drive it. Get into a certified shop to get this condition taken care of
now.. If there are excessive amounts of fuel fumes in the vehicle it can and
will create a condition it will flash over. Burning everything inside of your
vehicle. Which includes you and your family. Don't mess with it.
These fuel injected cars/trucks have high pressure on the fuel system and it
could have a leak from the fuel tank all way to fuel manifold rail which set on
top of the fuel injectors in the engine.
Please, for your safety, get it check out. GB you...stewbison
Three things come to mind. You may have an exhaust system leak. Or, the rear hatch is not closing good, or not sealing properly, allowing exhaust fumes to enter the rear compartment. If you drive with the rear windows open, the exhaust fumes will be drawn into the vehicle while the vehicle is moving. Just some ideas on where to look for the source of the fumes. Don't take the problem lightly. The fumes can be deadly, or at the very least, make you ill.
From where? you haven't given enough info, but put a large piece of flattened cardboard under the car to see if any is leaking. You will then be able to see what general area it's coming from--if there is a leak.
It could be a fuel injector(s) or even something very simple. When is the last time you had a tune-up, including a new fuel filter? If it's been more than two years, it's overdue. That means new oil, oil filter, air filter, fuel filter, and spark plugs.If your car has a distributor, you should also replace the distributor cap and rotor (cap).
Try to locate a specific area where the smell is coming from. Breathing gas fumes is not healthy!
