This is a great start!

I'm a bit confused which engine these two (green & red) o-rings are for.

In which entries in the table below (from post #28 above) do they go?

SIZE CONVENTION:
  • Metric
    • inside diameter x thickness (in millimeters)
  • SAE
    • outside diameter, inside diameter, thickness (in inches)
