Narrative:

The student and I noticed engine roughness and low right engine fuel pressure. We finished the engine roughness checklist and the engine resumed normal operation. At the same time we turned back direct to ZZZ and started descent to 8500 feet MSL. We notified ATC of right engine problems. After we troubleshot the systems by turning the fuel pump off we noticed engine roughness again. We turned the electrical fuel pumps on again and notified center of right engine driven fuel pump problems. Center declared emergency and we returned to our home airport. After evaluating our problems and establishing a plan of action we landed safely.
