Fuel filter o-rings?

[HK45]

Just got a new fuel filter for my machine. I see it has 2 o-rings but the new filter did not come with them. Do you need to order them or can i reuse them? thanks

I have changed my fuel filter twice so far and have not changed the O-ring mine has only one O-ring. But I just purchased 2 O-rings just in case the next time things do not go so well.
