I installed the gauge a while ago. Had to remove it now, and now I am putting my car back together.
I wanted to know if I can reuse that copper crush washer? or would an autoparts store have one?

EDIT: I also have a bunch of stock crush washers..the ones for the other side of the banjo line.

 

try thewashers you already have.

otherwise autoparts store or dealer should havewhat you need.
