Replacing Fuel and Brake Lines on the Cherokee 140

It has been awhile since I last posted on the Flying37 blog. Some time off after my dad's death was apparently needed. I have been flying a lot and hiking a lot and I'm going to get back into the swing of blogging starting today. First, my flying buddy Ron decided to replace the rubber fuel lines on the Cherokee 140 just because. He also figured that while the tanks were out it would be a good time to replace the brake lines. Nothing indicated that either of these lines needed to be replaced but since they were original factory items from 1968 it certainly wouldn't be a bad idea. There's a lot of screws to be undone to get the tanks out but with a powered screwdriver it's not such a bad job.

After getting the tanks off it became evident that the fuel sensors had been leaking at the seal for quite some time. Not a big leak, but who wants Av Gas in their wing? The fuel lines were pretty shabby. The rubber was rotten (the steel inside was fine) and they looked worse for the wear. The brake lines looked fine, but it felt right to replace them. The local A&P made up new fuel and brake lines and the fuel sensors were sent away to be rebuilt.

With everything else checking out okay, the airplane was put back together when the sensors returned just a few days later. That first test flight after maintenance is always a bit of a nervous time, but N6794J performed flawlessly.
