Fusible Link

I've determined that the fusible link is bad. The battery is good up to the connector part of the fusible link but not at the bulkhead. Is the wire from the connector to the bulkhead the actual fuse? What is the best way to replace it?

Should I get a fusible link from someone like Napa? Also is there a special way to remove the fuseable link wire from the bulkhead connector?

Thanks in advance. I'd like to get it running tomorrow.
