The NTSB has issued their final report on the fatal crash of my friend Al Lavender's Sonex in 2017.

Attention to detail. Fly the airplane no matter what. Let's be careful out there.

Thank you for linking the report, I am sorry for your loss.
For what it's worth, I recommend religious use of torque seal (visible paste that dries hard to indicate if a nut has moved) on all torqued parts including fuel/oil lines. Anytime final torque is made, apply a squirt of paste across the gap between the nut and the connector, and assume that any nut/connector without torque-seal has not been tightened yet. This even applies to routinely removed connections like oil lines for an oil change. Old hard paste is easy enough to chip off with a fingernail when a connector is removed, and fresh paste applied once reconnected.
