Does anyone know the proper way to close up the engine connection after a vacuum pump removal? After my attitudie indicator tumbled days after a solid IFR flight I contemplated doing away with the vacuum system and putting in two Garmin G5s which are certified as an attitude indicator and a DG/HSI. Well, I delayed the decision and had my AI refurbished by the manufacturer. Turns out, during a solid IFR flight a few days ago my vacuum pump failed completely- zero suction while in the soup. I safely made it home – partial panel training works, but now I’m definitely going the all electronic route. I’m going have all of the vacuum system equipment pulled, but can’t find definitive information on how to plug the vacuum connection to the engine. I will ask my mechanic of course, but wondered if anyone here has removed their vacuum system. Appreciate any pointers or links to resources.
