Is it possible to retrofit an O2 system

For what it's worth, my K has an aftermarket onboard O2 from when I bought it. It's got a leak above our heads somewhere in the interior. All the MX's I've talked to said they can troubleshoot it but it'll be stacks of cash, and the interior won't look the same. They troubleshooted everything up to that, which was already $$$. 

We switched to a portable one and it's nicer just having it there. Don't feel like you've lost much if you don't go the onboard route.

If they can't put the interior back to look the same, they have no business troubleshooting anything on your airplane.

It's one of the more/most reputable shops in AZ from what I can tell. Not that that's everything. My guess is that they just didn't want to.

my go to guy for all things Oxygen is @Scott Ashton. Aerox is his company and he really knows his gases. Scott has been a fantastic supporter of the Mooney community sponsoring the Mooney Summit in addition to being a Mooney owner himself. Questions? Scott can really help, albeit he is busy working his booth at SunNFun for the next couple of days.
