cp3 leaking from FASS fitting

My pump is leaking from the fitting between the line from my FASS and the injection pump, on the pump side. I talked to John with Floor It on Friday and he said he thought he had what I needed in stock and he would try and get it out that day so I could have it on Monday. He said they use a different fitting when they test the pumps on the stand, which would explain why it didn't leak for him before shipping it out. Tuesday has now come and gone and I still have a leaking pump, instead of sitting around for ups to bring me something, is there anything the local automotive store might have to seal up that fitting?

I took a picture as my terminology isn't always spot on...
