Here's a new one, and from the very experienced engine builders and mechanics, a new one for those I talked too.
While removing one of my injectors, I noticed some resistance above the normal break out force required to free the B-nut from the injector body.
In less than a quarter turn, the brazed fitting on the stainless line cracked right at the junction. Damage already done, I turned the stainless line into a pretzel before the line/fitting broke loose of the B-nut.
So, not sure what caused the fitting to stick to the nut to this degree, but a new line is on its way. Not sure what I would have done to prevent this, if anything.
Next time, if one sticks, and I catch it before it cracks, perhaps some mouse milk dribbled on the top of the B-nut, or some heat, or both.
Weird!
