ATC had asked me to maintain 7;500 FT altitude. An electrical fuel switch for the axillary tank system failed causing loss of power to the right aux tank and partial fuel starvation to the right engine. I was able to recover normal fuel flow to the right engine by switching to the main tank on the right. While diagnosing and correcting the problem I had a temporary loss of altitude which I quickly recovered.
A C-414 right engine lost power after an auxiliary fuel pump electrical switch failed causing fuel starvation. The pilot lost altitude while switching fuel tanks to restore normal engine operation.
