Had an A&p stop by yesterday before my engine start to look things over one thing he mentioned was not to attach anything to the fuel injection lines even Adele clamps. I have my fuel injection lines clamped thru adeles to pushrod covers I believe he said there was an AD out for that Lycoming put out for production aircraft. I thought it would be a good idea to keep those lines from vibrating and attaching it to the pushrods seem like the best idea . It also gives a place to attach the lightspeed high-voltage lines. Has anyone had a problem with that ?
