Mine have not "spun" and were screwed in very carefully to absolute minimal torque (just a little more than hand tight).
The leak I have currently is very minimal, only a few drops over the course of a couple of weeks of standing in the hangar and it only seems to leak when we have really cold weather (not so much of a problem now).
I will probably attempt Phil Bird's fix first before installing an oops fitting, the fix is very easy to do and requires only a 3/16 plate, drilled and tapped to screw onto the AN fitting and some Permatex #3 to go between the plate and the tank.
But with the warmer weather we're starting do get here now the tank is fine, no leaks for the moment, so this will be a next winter job.
Well, the leak has gotten bad enough that I need to do something about it so I will attempt Phil's fix as mentioned above this weekend.
This should work as long as the molded fitting does not "spin" when removing the AN fitting. Fingers crossed.
Initially it was only the large molded fitting that was leaking a bit but now it seems small lower fitting that is used to attached the fuel sight gauge also has blue stains around it. I will need to do that one as well I'm afraid...
It is worth noting I have never removed the fittings after initial installation and they were fine for the first 50 hours or so. Goes to show that they can eventually start leaking even if left alone. This was just a bad design and it's a good thing Sonex has abandoned these molded fittings now, unfortunately for me I already had my tank installed when they did...
