I have a 2012 jeep wrangler jk 3.6l pentastar and have a fuel leak. I can smell gas really bad inside vehicle but not much on outside. does anyone know where it could be coming from? when it has been parked overnight the next time I get in it it smells really bad inside, but there is no smell on the outside. I have to drive with the window cracked because the smell comes through the vents. Any ideas???? This engine is the worst!! I love the jeep but am tired of fixing it!
