The red arrow i would agree, yes. Notice directly south of the red arrow on the a/c line, it appears to be more clip but rotated down. Check to see if it was a portion of the bigger clip
Thanks Mustang5L5 and 96blak54, you were right. I put it back where it belongs.
I noticed a small ring on both AC lines just dangling loose on each of the lines. Where do they belong? You can see one on the pic below.
Interesting! To bad my a/c experience is with removal. I removed mine due to the 5.4l size. It all fit and really i didnt have to remove the a/c, but it sure did open up some room.
