Can breast pump parts be reused or should they be replaced?

Can I reuse pump parts or should they be replaced? I still have the same breast pump I used when I had my son almost 2.5 years ago. I plan on reusing the pump because it worked very well, I also still have all the parts that came with it like the tubes and stuff. It’s all been put up in a box in my closet since I stopped bf. I only breastfed for about a month maybe a month and a half. Could I just sterilize the parts really good and use them again or would I be better off replacing all of them? I can’t find parts for my pump in store anywhere besides online and the replacement parts kit for my pump is about $50 after taxes and shipping😅 obviously I’ll spend that if I have to but I’ve been on a tight budget lately so just wanted to see if the parts i already have could be “salvaged” or not lol
