Overall view of the fuel high-pressure duct.

It exits from the turbopump near the upper right of this photo, descends diagonally, and then turns 90° to disappear behind the engine.

On the S-3D, the turbopumps were mounted on the missile frame, forward of the engine's gimbal bearing, which meant that the high-pressure ducts had to allow for the movement of the engine; to this end, the ducts incorporated braided-covered bellows sections to provide the required flexibility.

Also note the LOX high-pressure duct, located behind the fuel high-pressure duct.
