Gas smell

There are times that when I shut of the car I smell gas as I get out of the car. My wife also says she smells gas in the car after a fill up. Any ideas what I could look for?

Re: Gas smell

Re: Gas smell

I had a vacuum leak a while back. Caused the car to run hella rich and I could smell gas at idle, and after I shut off the car.

What I would do first is check all the simple things first. Start the car and check underneath for drips. Let it run for about 10 minutes while doing this...even take teh car around the block to get it warmed up, stop and check again. Shut the car off and check again. Wait ten minutes and check for leaks again. You want to try to check every circumstance the car might be under for a leak.

After that go around and check your vacuum lines. They are the soft rubber lines that are about 1/4" in diameter and run from various parts of your motor to various components. Check for broken lines, holes in lines, and vacuum lines that aren't connected. In my case, I had a vacuum line with a gaping hole in it going to my MAP sensor, which gave my computer a bad reading as to how much air was coming into the engine and it caused me to run hella rich.

You can even buy a vacuum gauge for about 15$ and check to see how much vacuum you are pulling. Between the area of 17-22psi...or hg/m...whatever vacuum is measured in is what you are looking for.

EDIT: check out this link for some of the most of the locations for vacuum lines: Vacuum Diagram
