The line was there purely to show that the hose was not twisted when installed. Most all hoses have a line of some sort for this reason. The line was applied to the raw rubber hose before it was molded and vulcanized into shape. The line can be anywhere around the hose. GM specs probably specified that the line be visable when viewed standing over the installed part. That leaves plenty of room (about 180 degrees) for the line to apear. Same thing with the part number.

This is just like the assembly line codes molded into tires. The code was painted on before the raw rubber was molded.

So don't sweat the orientation of the line or the part number. Just get the size and font right and you will be OK. Duplicate an original if you want to be on the safe side.

I highly doubt that you will find many hoses with the lettering all in the same place on that many original hoses.
