Wrong fitting for AN PTFE?

[bigmoe]

This morning I was going to run my fuel lines from my rear mount tank. I had researched a while to order all the correct parts but I may have the wrong ends for the hoses. I'm using -6AN PTFE braided s/s line. This is the fitting I thought would go on the hose ends to attach the line to the fittings on the pump, corvette regulator/filter and fuel rail (returnless). I thought there was supposed to be a two piece end that threaded onto the line? Or Have I got half of what I need?, missing the collar that goes on the hose first?

(By the way when I am done I'm going to make a thread listing all the parts I used because it sure has been a confusing process)
