Good idea. Do you by chance know the specs for the O-ring. I could not find it in the IPC or MM. Thanks.

Thank you Paul for your explantion. I removed the line without any issues - as you said, there is a schrader valve in the fittig and there is no need to empty the tank for disconnecting the gauge.

My guess would be that something got bent if this problem suddenly occurred without any prior signs of gradually worsening interference. How was your last landing before this flight - do you recall anything unusual? Any noticeable intereference or change when you retracted the gear after takeoff on this last flight?You mentioned that no bends were detected - did you just eyeball it or did you check the tubes with straight edge? It does not take much of a bend to get some inrteference in Mooney gear.

I am considering getting a hangar set up as well once I fix the leak. It is not much, but still annoying. The fill port access is not very well designed and I had to change the fill port in the past. Fortunately, my local FBO guys are nice enough to bring the O2 cart to my hangar when I need a fill and I will connect the hose to the port myself. That way, I can only blame myself if the port gets messed up again.

Thank you.

Based on the IPC, the service manual, and inspection of the system in the plane, the line to the gauge is always pressurized and connected to the fill port. There is no shut-off on the bottle itself, other than the valve that opens the flow to the cabin ports. When reading the service manual, I get the impression that the bottle can be disconnected without emptying. Seems that there may be a Schrader valve in the fitting that goes from the fill port to the valve. I was hoping that some MS members may have personal experience with this set up.

If you do end up at KRHV, you may be one of the lucky pilots who have the "opportunity" to test fly the new wonder of modern chemistry - G100UL in your Mooney. Hope that your tanks are in good shape. Cursory earch of the forum will give you some ideas.

The tubing is fine, the leak is in the thread on the gauge. Probably just needs to be tightened, but the line to the gauge is pressurized even if the valve is in off position and I would prefer not to be playing with the fitting while under 1500PSI.

I found a minor leak by the oxygen pressure gauge in the cabin and I may need to disconnect the line that goes from the tank to the gauge to fix it. Can this line be disconnected from the valve without having the empty the tank first? My tank is almost full. The tank has Scott valve p/n 803216-03. Thanks in advance for any suggestions.

Bravo heater is not very good. Uggs sheepskin lined boots work well to keep my toes from freezing in the levels .

Most likely by someone with the "if it does not fit, get a bigger hammer" attitude who was replacing the tiedowns after jacking the plane up for maintenance. My plane suffered the same injury a while back. Apparently, it is not that hard to cross-thread and strip the thread for Mooney tiedowns. Helicoil and Lasar permanent jack point/tie down combo fixed the issue for good.

Superb! Enjoy it in good health.

I would start with the fuel injector. Partially clogged injector will cause lean mixture and higher EGTs. Also, borescoping the cylinder may be a good idea to see if there are any signs of damge to valves. I woudl not fly in its present condition.

My guess is that George will now declare the Cirrus to be painted with "inadequate" paint system and "poorly maintained" which clearly caused the damage shown in the video . After all, well maintained planes that use "proper" paint are fine when G100UL is splashed around. Sarcasm off...
