Title: Oil lines AN-8 or AN-10 Post by: Paul Bahnstormerz on April 28, 2015, 00:21:37 am I've used 1/2" aeroquip oil lines for years, but currently rebuilding the engine and looking at the oil hose, and fittings.
Is there any benefit to using AN-10 hoses for the full flow and cooler lines or stay with AN-8??
