I have an O-320 with a leak coming from the valve oil tubing. Is the rubber connector a Lycoming part of just a piece of fuel line?

Hose

Either will work. Lycoming STD 2180 or brand x AEL ST2180 or Aeroquip 303-6 hose and cut your own. For a homebuilt an automotive type clamp will work better than the standard worm drive clamp. If you cut your own I would make them at least 1/4" longer than stock. MIGHT help prevent future leaks.

?? Push rod tube or drain line?

Tube

Just a piece of fuel line identifies it as rocker drain tube connector hose. Pushrod shroud tubes are special gaskets at both ends. No hose.

Probably the best hose for that application is power steering return hose. It's specifically designed for hot oil under low pressure. And use spring clamps instead of worm-drive clamps. The hose in the pic below was installed in 2007 and still looks/feels like new today.
