Front Vacuum Pump

[frank.oconnor19]

Anyone have experieince with these going out. I have the rear one still operational, last flight showed front Inop. My question is do you think it is just the pump or do I need to start somewhere else.

Also anyone have an opinion on OH v. New. I have an all glass panel, Vacuum is just for running deice boots. So not critical except in icing conditions, which I try to avoid anyhow.

I am thinking about saving 300 by purchasing OH from Aircraft Spruce. Thoughts.
