Since that engine runs fairly low oil pressure, you could simply replace the flexible part with a piece of high-pressure rubber hose like a fuel injection gas line for a car equipped with a Bosch gear-type fuel pump. (Volvo, etc.) Those pumps develop around 70 PSI at times. A 6MM line should be very close to the 1/4" inside diameter line you've got now. Carefully file away the crimped sleeve at both ends of the leaky line, remove the damaged flex line, slip a new piece of tubing on, and secure the hose with worm gear type hose clamps. It should get you back on the road until the replacement line arrives.
