Nope, that is low pressure, fuel return line (returns fuel back to the tank.) There are 2 hoses that connect to the out banjo: one little one that connects to the injector return line, and a big one that returns fuel back to the tank. This fuel line eventually decays with time and heat and should be replaced if it gets brittle. I recommend using the OEM cloth-braided stuff, both are available aftermarket from OEM VW suppliers. The cloth-braided fuel return line has a 7mm inside diameter.
