I'm smelling gas fumes inside the car when I'm idling but as soon as I accelerate it goes away

Gas smells come from leaks or the engine running too rich ( over fueled ). You need to inspect for any wetness/dampness around the fuel lines/rail and injectors if the smell appears from under the hood. If the engine is over fueled, a scan test can be performed to find out why. Sometimes oil leaks on/around the exhaust system can also give a fuel type smell. Have the vehicle checked for this also.

Strong gas odor inside van and outside. Check engine light came on today. No leaks drives fine. just passed emmissions 4days ago

Good thing you passed before the engine light came on. You should mos def get the code from that engine light. If you smell gas you have a leak in the system. Same thing happened to me i had to drop the tank and change the seal around the lid of the fuel pump housing because the smell was coming from under the car and in the car. I also followed my fuel lines and saw some cracks forming so i replaced those and the gas cap for the heck of it. Only $20 for everything but make sure to pull the code first. It reslly makes things easier.

Car has gas smell when heater is on

my question is do you smell gas when outside the vehicle? chances are it is pulling "fresh air" from outside the vehicle and might be pulling vapors due to thew fact you have a gas leak under the hood. check your engine while running and if a gas leak is seen. turn it off imediately and repair it. do not drive it until then. happy holidays

I drive a 96 honda's been smelling like gas every time i drive it and seems to lose gas faster than normal. Would this be a possible gas leak? How much would this cost to fix approx.? I just...

hi, the problem is the gas could be leaking from several places the most common place is where the metal pipes come out of the tank and join to a rubber pipe this is the usual place of a leak.

But as you say you smell gas when you drive the car if you mean whilst driving the car you actually smell the gas inside the car then this indicates that the leak would be coming from under the bonnet as if it was leaking at the tank then you would only smell fumes when parked up or getting in and out the car.

Now as it looks like the leaks under the bonnet then the likely cause is going to be where the fuel pipe joins to the fuel injector rail as the engine vibrates and this pipe dont then this causes this pipe to split.

Now as for costs your looking at about an hours labor but as i live in the uk and hours labor here would be between 45 and anything up to 90 pound an hour depending on where you take the car (main dealers your looking at 100 pound to 150 pound per hour)
As for parts a piece of pipe would only be 5 pound or so so the actual pipe would not be expensive.

But you can never guarantee its going to be a strait forward job the leak may turn out to be a corroded metal fuel pipe from the tank this is not very likely but does happen from to time now this would cost between 25 to 35 pound for the pipe.

So you would have to work out the exchange rate to get rough figures but in uk i would say about 75 to 100 pound to do the work and get the car back to normal.

Let me know how you get on or if you need further assistance ok

Many thanks for using

Smell of gas while driving

If you smell gas while driving, check for leaks first.
Look under the chassis near the gas filler neck. Check under the hood for raw gas odor around the engine. If your hoses are not leaking, your car may need a tuneup. It could be burning too rich.

Smell of Gas When Driving

Given the age of the car, it is likely that there is a leak in the fuel line from the tank to the engine compartment. It may be leaking slowly enough to give you the smell, but not fast enough to actually drip on the ground, evaporating before dripping.. The car needs to lifted up to examine closely all lines under the car. If you can, put it up on ramps and crawl around underneath with a flashlight, NOT an electric drop light. If you can not safely get the car high enough to get a good look around, take it to a garage and get it up in the air. Tell the mechanic that you want to see the problem. Don't let them sell you a bill of goods. Insist on seeing the leak yourself. If you are lucky, you may be able to just have a section of line replaced, but it is likely that most of the line will be corroded to the point where it all needs to go. There is also a good possibility that the leak is under the hood somewhere, and the smell is drifting in through the duct work into the cabin as you drive. Also, driving with the windows may actually pull the smell into the car from under the car...Good luck. Chip
