Saving the Oil Pressure Line Connection

[Carpenterman]

I'm removing my 617 engine and I couldn't get the pressure gauge line at the filter housing off without cutting the line as near as I could get it at the fitting. No matter how I tried I couldn't keep the line from twisting with the fitting. I thought there would be a ferrule of some sort on that end just like at the gauge and I could refit it later.

After removing the fitting and then searching around I see that the connection is different, although I'm not clear as to what it is or whether I can reconnect the cut line. Is it possible to do this?

If I have to I can use the line from my parts car, but I've got enough to do without pulling clusters.
