Welcome to 2CarPros.
Since you smell gas but don't see any leaks, I have to suspect there is a leak in the EVAP (evaporative emissions system).
You said there was a faint odor. Can you tell me aprox where it was coming from? Was it the rear of the vehicle, side, front? Also, I need to know if the check engine light is on.
I attached a picture of the EVAP system hose routing schematic. It could be one of these hoses leaking. It won't leak raw gas, but you will get fumes. See if the diagram helps you. Each component on the diagram is numbered. Here is a list of what each thing is:
1 - EVAP Canister Purge Solenoid Valve
2 - EVAP Canister
3 - Fluid Level Vent Valve
4 - Vapor Re-circulation tube
5 - Fuel Fill Neck and Fill Cap
6 - Fuel Tank
7 - EVAP Canister Vent Valve
8 - Vent Hose/Pipe
9 - EVAP Vapor tube
10 - EVAP Purge tube
11 - EVAP Service Port or Service Access Connector
You may also want to check and confirm fuel pressure isn't too high indicating a bad regulator. Here is a link that shows how it is done:
Here are the specs for your vehicle. If you do this, let me know what you find.
Fuel Pressure (Key ON, Engine OFF) .................... 345-414 kPa (50-60 psi)
Should not decrease more than .................... 34 kPa (5 psi) in 1 minute.
Let me know about the check engine light.
