Ok guy's today was the first day that I filled the fuel tank on my new to me 96 Sentra. What was very disturbing was I topped of the tank as I always do on every fill up with every vehicle I own. But this time I ended up with a heavy smell of gas?? Well I drove up the road a couple of miles to a store and got out and looked under the car and right wear the fuel lines go into the plastic tracking headed towards the front of the vehicle there was fuel leaking? Almost like there was a vent line that overflowed there?? I can't imagine that a vent line would be anywhere near there because the exhaust pipe was in close proximity?? What the heck happened hear? Did I simply overfill the tank or is there a bigger problem???
