Hi, I buy at 95 lesabre custom couple days ago on smell to much like gas when is idle in my driveway I look for any leek but I don't see anything, but the car don't had the catalytic converter, it's can be my problem of the smell of gas or keep searching for it all over the lines. Thanks in advance for the help...

 

You can check the fuel pressure regulator. Its located on the fuel rail on top of the motor. Pull the hose off of the top of it, and if there is any gas leaking from it, or if you can smell gas, it needs to be replaced. As far as the cat, I don't think that would cause the smell of gas, but you should get one for it as it is illegal in most places to run your car without one.

 

There is a vapor canister that is supposed to capture all gasoline vapors so they don't go out into the air. Look for a hose either broken or off allowing the vapors to escape.
