I suppose because the threads are too tight fitting at their minor diameter when tightened up for it to leak into the inside area of the fuel pipes.
And it did not happen. I had no leaking into where the fuel flows.
Solder has a viscosity thicker than water when liquid and it has surface tension.
Any time soldering pipes, there must be a loose enough fit up to actually draw the solder into the fitting. There must exist a sufficient clearance space for solder to flow into and fill a space.
