Yes but a plugged line will also do the same. As in falling apart internally and creating a one way valve.Been seeing a lot of that over this past year.
There are recommendations there and there as to replace them lines at about 6 yrs. New DOT regulations now reguire that all such pressure lines on vehicles be dated, little date band over the line. My new Spiegler's have such but not the OEMs on my bike, 2003...predates the new regulations.
