Question ABout D15 Fuel?

Hi,

What is the red kinda "Rope" material line that goes to the intake manifold. It comes from a canister that is right next to the fuel filter.
Is this the fuel line?
Is it ok to disconnect it and then block it off with a vice grips?

Thanks
Owen

its a vacuum hose. Fuel line is connected to the fuel rail.

You should be fine taking it off, but be sure to put it back before you start the car up again.
