Cracked brake reservoir

[Ralphbrown]

Hi there, recently took apart my braking system and was putting it all back together today. I was using an eezibleed kit to bleed to brakes and found there was a hairline crack in the reservoir. Can only see it when the bleed kit was attached. Was hoping I could just buy another one but struggling to find one. Any ideas what I could do?

Thanks
