View of the lines leading to the engine's heat exchanger.

Picture 2 of 3.

From right to left, the lines are

  • Helium supply line
  • LOX supply line
  • Helium return line
  • GOX return line

Note that each supply line is of a smaller diameter than the corresponding return line. Also note that each pair of supply/return lines are joined by a bypass hose.

Under the fitting terminating each line is the actual entrance to the heat exchanger coils.
