Hello Everyone,
I am currently in the middle of installing dual G5s in my -4 and have been going at it with a phased approach. I currently have a single G5 installed with magnetometer and OAT. In order to install the second G5 I will need to remove the DG, but I'd like to remove the AI while I'm at it. I'm not quite ready to pull the whole vacuum system yet so I was wondering if simply capping off the vacuum lines was acceptable. My initial thought is "no" since the vacuum pump is pulling air from the cabin and needs that constant airflow to function smoothly, but on the other hand you'd think there would be a pressure relief valve built in somewhere in the case of a clogged indicator or something. I'm unable to really find any information on the internet about how this system actually works.
Any input would be much appreciated!
Thanks
