I'm installing a "pre-owned" engine in my RV-9A. The engine was recently on a certified aircraft. There is already fitting in the pressure port, but I don't know if it is a restrictor fitting? It does appear to be steel. I'm really afraid to remove this fitting for fear of damaging it and/or the port trying to get it out.
One option would be to assume that it is a restrictor fitting and just try and use the fitting as is.
I've enclosed a couple of pictures. The directions say to install the fitting "45 degrees outboard and 45 degrees down." The fitting is installed 45 degrees outboard but is about 30 degrees up. I assume that this will interfere with the engine mount, but I'm not sure. Will the 30 degrees up be a problem?
What are the chances that this is a restrictor fitting? Is there anyway to tell?
If I either have to or decide to remove it, how is the best way to go about that? I've read that heating the area up with a blow torch will usually soften the sealant enough to be able to remove it. Are we talking a micro torch or a regular sized blow torch? The edges of the fitting have been rounded a little so I can't get a solid hold on it with a wrench. Any suggestions about how to remove this fitting?
