Dennis,

I'm new to Crossfires (and the thrill has not worn off any) so this may not be helpful. I suspect the line is polyethylene or something similar. That's been used for decades, and is the orginal line material on my 67 Dart GT convertible. Compression fittings should be available for polyethylene or steele lines. There will be a fitting between the cut ends. Slinde a nut over the end, then the compression "washer," then tighten. I've used them on water lines and even brake lines, with no failures ever. Unless there is something unusual, the compression fitting should cost only a few dollars.

Good luck.

Michael
