View of the oxidizer feedline.

Picture 1 of 2.

Note the two cut away areas: At left, where the engine's feedline connects to the Service Module's line, is a vaguely conical screen; I assume this serves to filter any particulate matter which may have contaminated the oxidizer supply. Just right of center is the feedline's bellows which allows the feedline to flex as the engine gimbals.

The oxidizer line, afer partially wrapping around the engine horizontally, runs vertically to the valves at the forward end of the engine.
