W164 ML63 Fuel Smell Drivers Side Rear

Hey everyone,

I’m trying to chase down a fuel smell by the drivers rear tire of my w164 ML63.

the fuel tank is there so I’m assuming it’s either the seal on the fuel pump/tank or maybe the evap system.

As I look tomorrow are there any common problems that everyone is seeing with these cars?

- no check engine light
- MPG seems normal
- we smell it when it’s parked in the garage
- there could be codes, haven’t read them yet.

Thank you!

Negative to my knowledge. My ML63 is going on 17 years old and no fuel smell. I’d probably look more towards the evap system, a crack in an evap hose would do the trick.
