After driving in a hot day, I will get fuel smell coming from my engine bay. I had the fuel feed line going to the fuel rail tightened(at the rail) just a few weeks back. It solved the fuel leak/ smell which was very strong regardless of the temperature. I checked the same place and there appears to be no leak. What could be the problem? I can't seem to trace the source of the leak with my nose.

 

check filter and line fittings
check your injector seals
if using aem fuel rail, check the allen bolt on top
check fuel return line
just follow the fuel trail you should be able to narrow it down.

Yep, the o-rings leak sometimes.
