I would get a whole new line. Measure the length of the line that is on your truck and then head over to an auto parts store and spend $5 to buy a new line with metric fittings. They usually have lines in length from a foot all the way up to 5 feet or so. Then you can bend it to fit your truck. A cheap bending tool will work, or use objects you have around the house like soup cans, pipe, or other round objects to get nice bends that match the line on your truck.
