Well I did go back and check. He swears these are not metric and nothing on the green tag says anything except 1/4" OD. He said he had been selling this same line for years and no problems.
Mine had a green tag on the line and the nut was steel colored also.
He showed me his metric lines and they did have a GREEN nut, but a purple tag on the line, and did say 10mm.
Soooo back to square one.....Guess if the film of grease don't work, I will replace them all with NAPA.
By the way, I don't even know what brand name his store is. It just goes by: City Auto Parts. He does have access to Cardone brake parts.
Thanks to all.
