Overall view of the forward end of the engine.

At top is the fuel turbopump, with its fuel inlet; on its lower left is the alcohol duct, which carries the high-pressure fuel to the fuel inlet manifold; on its lower right is the steam duct, used to vent the turbine's exhaust gasses, first through the heat exchanger and finally overboard through the steam vent on the tail unit's aft face.

Note the ID plate on the engine mount at upper left.
