I found the on/off valve. It's a small brass valve near my knee. Sort of hard to see. It looks like it is definitely leaking at least there. Previous owner said it just stopped working. Not disabled. That was a full size iPad, the mini is on the way. I've got a yoke mount for it. The adjustment knob is part of the turn coordinator.

I have a new to me, 1967 m20c. It has a PC system that I doesn't work. At least I don't think it's doing anything. Although when I fill one tank and the other is empty (fuel leak), it's not that noticable on the imbalance. Anyway, what kind of disconnect switches were used. I have an electric yoke switch but it's wired to my ptt. Where are the servos/actuators located? Is there a methodical leak detection technique?

i believe the 830 is only certified to be a backup system. so you would need to leave the old gauges in. thats what im planning on purchasing also, but im not sure if the original fuel senders talk nice to the 830 or if new fuel senders for the 830 would talk to the old gauges. does anyone know??
