Well ****... I did something bad tonight. The strainer shown above went in and came out fine, and I was curious how the other one fit in the other fuel tank and it went in fine, I didn't over torque it, and galled the threads on the way out.
Since this is a QB Wing, this is my first dealing with aluminum fittings and I'm feeling pretty dumb right now.
I have little faith that the VA-141 will clean up when I acquire and run a 1/2" NPT tap through it, but maybe it will.... It's too bad this VA-141 doesn't get installed from the exterior.
