The oil and fuel lines in my 1999 Mooney Eagle need replacement according my mechanic and Continental Tech Support. I have the rec "C" lines which are rated for 7 years. He is recommending to go to rev "D" which is teflon and is rated for 12+ years.
Anyone has done this on io550? if yes, any recommendation on where to get the hoses made for the best quality and price?
