Hi all! I just purchased a set of lines for my 1995 suburban k2500 4L80e. The old lines had a quick connect going into the cooler and the new replacement lines do not. The lines that inline tube sent me have a thread compression fitting. I ordered them online and am told by tech support that my truck should not not have the quick connect and that gm must have used some leftovers. They told me to go to chevy dealer for a 1/2 x 20 inverted adapter. I'm waiting for it to come in but gm dealer doubts that their part is an adapter, just a quick connect as is normally on this year. Anyone have any ideas other than returning these. Already tried local parts and even plumbing section at lowes for a bushing. Thanks.
