My 2003 expedition with 182,000 miles. Great truck, but recently has formed a strong gas smell around and in the vehicle with no visible gas leak. Just the smell. After sitting over night when you jump in, vehicle off, it smells like daddy's old farm truck. Ive read many threads but all stear towards off the main topic of why i smell gas. Any thoughts from a pro or someone who has had the same issue please, im all ears thank you.
