Sorry. You will not be able to reuse that olive on that line. It should be easy to find another. Anyone
who works on oil or gas heating systems will have the right size. At the very worst, get some olives
(not just one) from a Morgan dealer. The lines break often enough and they should all have what you
need at hand.
Using a small pipe cutter, cut the line, slip on the new olive and tighten at the junction. (Be careful
to leave the fitting on the line before you put on the new olive and tighten.)
If you have decided to run the risk of the oil lines, then get a threaded plug to close the oil feed at
the engine. Carry it in the car. It will probably help you get home one day.
