Softer oil breather hose?

[phunt]

I have modified the placement of my oil tank. So the stock hose for the engine breather vent to the tank won’t work. That stock 25mm hose is pretty stiff. Is there any hose that is more pliable and easier to run? AN-16?

You could use nylon -16, maybe over kill for vent line. There are many 1” ID fuel and oil lines on amazon that would work.

I found that the URO breather hoses don't fit over the breather flange, even with considerable effort and lube.

I bought some braided rubber hose from Aircraft Spruce to use for the crankcase vent plumbing. Just looked, and they have something called Stratoflex 11 that looks like what I got. Available with large ID to fit this application.

Sometimes you can clean up the breather hose by rerouting it with a 90 degree connector.
They were used on 911 SC CIS engines. 911 110 286 00

Thanks John, we're checking out out that hose.
