So, I was just at the grocery store and was getting in my 4Runner (3vze), fired it up and all of a sudden I caught a huge whiff of fuel. After driving it had gone away. I made it home and started to investigate. I looked all around the engine bay with no signs of fuel leaking that I could see. So, I started it up and smelled it really strong again. I narrowed it down to the drivers side of the intake manifold and faintly on the passenger side. I started researching on here and saw that the pulsation dampener should be checked as well as the CSI. I will check both of those in the morning but until then does anyone have any ideas? Please help me. Thank you all
