I would like to know who makes a quick disconnect tool for the 2000 LS 3.9 Liter line from the A.C. Compressor Manifold. I measure 1 inch but the biggest size that is available at the Auto stores is 7/8”. The Ford Manual refers to Rotunda 412-039 (T84-19623-B) kit but the largest size there is 3/4”. I tried the nylon 7/8” that leaves a gap but I can’t pull the line apart. It will rotate a little. Also tried WD40 and oil. Anybody know who makes the correct tool? It might be European since many of the parts are shared with the Jaguar S Type.
