Are you talking about the metal clip? If so you don't need it, I'm pretty sure it was a add on clip for a recall. If you want to cvall ford to see if the recall part # is still being made you might be able to get one that way. Myself, I would not even bother.
i lost my small one when i did my engine build! if you run the zip tie threw the holes instead of around it. it will hold thats how mines set up and my aeromotive 340 hasn't blown the return off yet
