strange hose by fuel filter

[JoeG]

I changed the fuel filter tonight and noticed something strange. There are the usual fuel lines running from the front->back.. two of which go to the fuel filter. Then there is another one in the same bundle that dead-ends right next to the fuel filter and is just hanging there open. Any idea what it could be?

Thanks,
Joe

Probably from the drain inside the filler door.

Ahh yes. Thanks!

On a lot of the earlier cars, the fuel vapor canister would oversaturate and fill the cabin with a raw fuel smell. The fix was to route a hose to the rear of the vehicle to vent the vapors behind the passenger compartment.

This may be what you saw, or perhaps it is the filler drain.
