It seems the original fuel return pipe from the injectors to the filter/tank had barbed fittings on each end, including the end that went to the top of the fuel filter. It was broken off when the engine was taken out of the original truck. The replacement pipe (ERC4480) has a male compression fitting on the end. Is this 6mm or 1/4in?
