You are aware that it is mandatory to replace all rubber hoses every
five year, regardless of condition? Have you checked when it was last done?

Best place is behind the engine. You should try to avoid creating "high
spots" in the coolant lines where air or vapour can collect.

Keep routing as simple as possible and keep it as low as possible. Oil
won't siphon out, unless there is the tiniest air leak somewhere in the
system. A few months without flying and you have air in the oil system,
if the air reaches the oil pump you will suddenly loose all your oil
pressure.
