I happen to own a 2002 T&C 3.8 160,000 miles. I recently experienced gas smell from vent and outside right front of vehicle. I looked everywhere and first thought it came from the plastic fuel line to fuel rail connections, I removed the upper intake to expose injectors but no leaks there either. With no other signs I took a chance and twisted the fuel regulator cap sitting on the fuel rail. (Caution: don't work your fingers in on a hot running vehicle, plus it sits 3" from the coil pack). The next day the fuel smell and visible signs were present; the cap's o-ring was leaking.
Use an led flash light to peek at that area just to the left of coil but remember, if you twist it, you must replace it!
I replaced the fuel rail and all 12 injector o-rings. (I do not recommend aftermarket fuel regulator kits costing $120) because the complete rail (with cap) from the dealer cost $68. The job took under 2 hours but I recommend having a professional perform unless you've done this before. Consult the guide to release fuel pressure, fuel line, handling gas, etc.
