Technically you should replace them once you've loosened the HSN housing to rotate the banjo. BUT as long as you do not overtighten the housing, you move it a couple times without fear.
However, after that go ahead and replace the washers.
Unless the housing was overtightened from the factory, I've never had to replace them.
