When driving car you can smell gas. I cannot find anything leaking, but the smell is quite strong. I don't have anymore details, the car smells of gas fumes. I can keep telling the same thing, over and over, but the question is still the same. I keep smelling gas fumes, but cannot detect any leaks.

Use a gage and check fuel pressure. See if pressure will hold for a bit, with everything off. If it won't hold, you may have a leak? Another possibility is your evap system leak/fumes. Check for applicable trouble codes, some of the national brand autostores will check codes for free.

Smell of your crankcase oil dipstick. Does it smell like gas?

Two elusive places to look are the o-rings on the injectors and the top of the gas tank. If an o-ring is leaking it can do so slowly you may not see the gas unless you look real closely where the steel tube sits on top if them. For the gas tank you have to look all around it for signs of a stain running down one side.

Also look under the sides of the car for a wet steel line. Those are more likely to leak closer to the rear tire.
