In my kids car, inside trunk on passenger side, close to wheel well, there is a black 3/8 ish ID hose. For what? Does it have anything to do with fuel venting? We smell fuel sometimes. Filler tube looks ok. 1999 impreza L

probably goes to the charcoal canister?

 

older soobs sometimes have rusted holes in the filler neck behind the plastic cover. that will smell.

Nothing related to the fuel system inside the trunk unless someone has run a new hose somewhere to replace a rusted out steel line.

 

Passenger side near the wheel well?

Where does it come from? Where does it go?

Cotton eyed joe!

is it thin and corrugated? split down the side? - maybe related to some wiring???? prev. owner had an amp in the trunk?

 

 

yeah just trace it, seems kinda hazardous if fuel vapors come from it into the trunk!

A picture would go a long way.
