Tonight I secured the fuel lines between the wing root and fuel selector valve.
I installed and torqued the bolts holding the plastic fuel line clips.
I also made a realization that I have used the wrong product on the NPT fittings; fuel filter, fuel strainers, and fuel tank drains and plugs. To address the issues, I removed all the fittings and cleaned all the threads with acetone to remove the fuel lube I had mistakenly used. I have ordered some Loctite 565 which I will use in it’s place.
