Just bought a 97 Civic LX automatic with 168,000 miles. 2 mechanics within the last 2 weeks (1 to do my oil change and change the fuel filter and the other mechanic to do a transmission flush) said whoever had the car before me took great care of it and there are no leaks of any kind. I notice every morning that my garage smells like fuel. There are no visible leaks under the car. Any thoughts?

 

Have you actually climbed under the car or did you just look from teh side?

 

do you have any lawn tools or gas can in there ? check that the gas cap is on tight

 

look for leaks around fuel filter. turn key to ON and pressurize fuel system and look for leaks amd/or seepage.

 

if I fill mine too much, I will smell gas for a day or so. And I have Zero leaks

 

This^ is definitely the first place to start, given that the fuel filter was replaced.
