The fuel inlet lines to the fuel valve only needed a slight modification to get them to hook up. But the fuel outlet needed a new line run. I got that done but it took me two tries. I ended up making the first attempt too short but the second one was good but I needed to bend it to the side so that the elevator controls wouldn’t hit it. I will say I might end up switching to braided flexible lines as many of the others have done. I don’t like the bends in these fuel lines but we will see if it leaks in the future when I get it all hooked up to the fuel tanks and run fuel through it. It will be a few more days till my next post as I will be going to Washington D.C. for a cybersecurity conference.

Rigid fuel lines are great for long runs; however, transitioning them to a flexible line towards the end of the run facilitates an easier connection to whatever that end-point is (e.g., fuel selector valve, engine, etc.). This approach also help dampen any NVH that may have traversed through the rigid lines. Over the lifecycle of the airframe the rigid lines are permanent, but the flexible lines will need to be periodically replaced. Having shorter runs with the flexible lines makes that future maintenance job easier. Keep up the great work!
