Any auto parts store, even an imitation one like Auto Zone, will have a replacement oil line kit with all the fittings you need to replace the line from the block to the gauge- - - -not do a patch job on a 65 year old system. New line, new compression fittings, and drive on!

Get the good-quality kit with a copper line, not the cheap plastic one.
