Filled up my car with GAS, now everything smells like gas

Yesterday i filled up at BP gas station, got full tank, came home parked the car in the garage.
My room is upstairs and i woke up in the middle of the night from gas smell. The whole house smelled. I opened up most the windows and opened up the garage door a little to get rid of the smell. The whole house smelled like gas, i actually felt sick. Now that everything is ventilated the house is fine, garage still has a little gas smell to it but the car inside still smells like gas, not too bad but its noticeable.

Anybody ever had this problem? What could it be? Its not the 1st time this happened but it was never this bad!! Its not leaking any gas and i didnt spill any! Please help!

I would take the car an wash the undercarriage 1st. I think if gas spills it will evaporate very quickly but the smell will remain.

Boing, do you ever overfill the tank? I always stop after the first click. I've done full top up( pass the 3rd click) on my previous vehicle and I could smell the gas as well.

hey, Rookie I always thought you had the same rims! but no! I was just looking at your Sig pix!

Had an issue like this on my Benz S500 after the radio shop installed the the amp behind the rear seat guess that's where the tank is.

Thats weird....But for it to be that strong of a smell it sounds like its a big leak or it spread over a wide area, perhaps under the car as you drove..

My wifes lincoln LS had a similar issue like this and it was a bad gas cap..I doubt thats your problem but i hope you find it before it causes a bigger problem.

Boing, you definitely have a leak. Sounds like a slow leak running thru the under shields inside. Maybe that's why u can see it? Stop driving it bro. You are driving on a time bomb. Any electrical spark or heat contact may cause an explosion. Putting yourself and other in danger. Have it checkout asap.

Thanks guys for all the info. I never overfill with gas, this time i did stop at first click just not to spill anything. It happens everytime i fill up, it smells for like a day and then goes away but this time i never had it smell so bad. For sure i will be looking into it just didnt know if anybody has same issue and what was the right way to fix it. But ill look into it and see what happens.

Wife had this happen once. Someone before her spilt gas, it soaked into the soles of her shoes, had to buy her new mats to get the smell out of the car.

House didnt get too bad but she always leaves her shoes in the entryway.

The house aired out pretty quick once i got the windows open and the garage but it was crazy that such thing happened. Woke up at night smelling gas, thought someone is trying to poison me. LOL

You will probably have to get the gas system smoke tested to find thel leak. I. Would also expect the Check Engine light to light as the system iis monitored for leaks.

Boing,

My first thoughts were that this could be a bad seal on the gas cap, however I am not sure that that wouldn't throw a CEL. I agree with Andy760 that you need to have a smoke test to see where the leak is.

One thing I would recommend is not parking your car in the garage until you get this worked out; especially if you have any gas powered appliances such as a water heater or furnace as these vapors are extremely flammable. Furthermore, the vapors can be harmful to breathe.

Thanks for the info guys! Where would be a good place to get that done? The weird thing is that it only happens when i fill it up. I know long time ago i remember some people saying everytime they fill up their car smelled like gas but mine was always fine until recently. So something is wrong for sure. The smell in the garage was pretty strong, door to the garage is closed and my house is just 2000sq ft but it smelled pretty bad. So far the worst thing that happened with my 7 probably. LOL

Okay so today i went and filled up a full tank of gas, i was completely out so got full tank, no everfill.
Get home right now and park the car in the garage, put cardboard all over the floor. 20 Minutes later the gas smell is crazy in the garage, i pulled the car out and parked it outside and sure enought there is a wet spot on the cardboard and stinks like gas. I looked under the car and the gas tank is wet. Right now hard to tell where it coming from but kinda looks like it might be the seal where the little pipe goes into the actual tank. Now i just wonder if that seal is sold separately somewhere or what?
Hopefully its an easy fix. Anybody worked on that kind of problem before?
