fuel lines

Went out to move the mazda around (dollies) and I noticed a fuel line hanging, currious to if anybody knows where this line goes it it closest to the passengers side and this truck has the webber conversion.

Pictures!
All fuel related hoses are on the passenger side.

Sorry, should say farthest to the passenger side.

Does the engine start and run?

Yes it starts and runs but i currently have the core support off and i put it on dollies to move it around the garage and noticed this fuel line hanging, i tracked down everything but seen no place for this particular line.

Then it is not the fuel line. Probably should go to the vacumn canister to draw off fuel vapor from tank.

AC evaporator condensate drain?

We need photos !!! Especially if they're of your truck !!

There is no charcoal canister and it is a line on the passenger side with the rest or the fuel lines, I removed the entire ac unit from this truck.

Hook it to an unused vacuum port, see if the trucks performance suffers?

It's just the vent line from the fuel tank. Let it dangle, or trim it back some. Either way, it won't make a difference without the charcoal canister.
