I?m close to installing my oil cooler lines. In all of the reading I?ve done about homebuilding, I seem to remember that somewhere it was recommended to use steel fittings on the engine for the oil cooler lines. Has anyone else read this? If so, where? Is this correct?
Also, I?m mounting my carb/FAB. The Lycoming manual shows that the safety method for attaching the carb to the sump is with locknuts in addition to the plain nuts. This is different than the older certified aircraft that I am familiar with (safety wire and castle nuts). The threads on the sump studs are 5/16?18 course threads. All Pal nuts and check nuts that I?ve seen in catalogs are 5/16-24 fine thread. Where have others purchased these locknuts?
Thanks in advance,
Cameron Smith
