Actually more voltage makes the pump motor run cooler and much more efficiently. It is better for the pump. But to work with a E67 PCM that uses the FPCM it has to be wired correctly. You need to power the FPCM with the higher voltage, not just the pump.
Think of it this way. What is harder on your power window motor? Trying to raise the window with a drained down battery and the motor struggles to raise the window? Or putting the window up with a fully charged battery and the window raises quickly and smoothly?
