Fuel Smell inside Car

A leaking fuel line can be discovered by looking for gaspuddles under your car when parked. A fuel-injection line may also leak, causing you to notice the smell of gasfumes during and immediately after driving. A fuel-tank vent hose may also leak, causing unburned gas to exit your fuel system as vapor.24 Apr 2015

hi have your mechanic check your fuel tank at the top were the hoses are sometime the hose clamps give way and may have some fuel resadue on the top of the tank

I'm not sure you would smell a fuel leak from the tank while driving, the tank is located to the rear of the cab, under the bed on the driver's side, you may however have a leak in or near the engine compartment. If this is the case, yes a fire is possible. If you smell fuel when you come to a stop, it may be your fuel cannister, or vent lines are leaking which should trigger a check engine light.
While the engine is running, Check the fuel rails and schrader valves on both sides of the engine manifold for leaks. You can also turn the key to the "RUN" position (do not start the engine.) this will cycle the fuel pump to run for a few seconds to pressurize the fuel system, and you can then check for a fuel leak.
I hope this is helpful to you.

I had the same problem with my 2005 Honda Accord. I would happen only sometime but is a distant odor I smell from inside the cabin. Older Hondas sometimes have gasket problems that leak small amounts of oil onto the exhaust manifold. Ask the mechanic to go check the valve cover gaskets. They replaced a new gasket to my car at the Honda dealer and I haven't smelled that burning odor since then. Good luck.

Usually, what you smell inside the car is coming thru the vent from the engine compartment.
So it could be a leak around the engine or the vapor canister. Its possible the canister gets overloaded from time to time when the computer vents the gas tank to the canister. A very small leak can be a very strong smell inside the car.

Check fuel lines going to the engine may need to be tight,or crack.

Have the entire fuel system inspected for leaks this means it has to go up on a car lift. Do this soon as there is grave fire danger here.

05. Fuel pump has died! It's located in the tank .

Your car is running extremely rich and the smell you are experiencing is raw fuel in the catalyst. If you keep driving this way the cat will clog and need replacing. You probably have one or more defective ignition coils, or you coil driver stage has gone bad (mounted inside the air cleaner housing)

Had exact same problem on my 96 cavalier it was a leaking fuel injector.
