source for PCV hose

Tony:
You are fine without the PCV - many older boats didn't have them. The logic being that in salt water use the throttle is open for long sustained periods and there is little or no engine vacuum to evacuate the gases from the crankcase anyway, so they were just vented from the valve cover up to the breather. It makes more sense on tow boats used for skiing - they run hard through the course and then throttle back and the vacuum is high enough to pull the gases through the PCV.

I just built an engine for my Fish, w/o a PCV. There is no vacuum port on the Marine Holley and if you pipe it into a runner on the intake that one spark plug will receive all of the gases and be fouled in short order.

Gary,
I believe it was California in the early 60's that required PCVs (or something similar) on cars.
I'd hate to see their smog today if those emission control efforts had not been made then.

Actually, I'm probably going to re-route the PCV circuit on my boat. (I've said that earlier here.) If successful, I won't need the "curly" hose pictured above. I've been working on that project this past week.

Per you request, and FWIW, here's the
original routing:

NAPA, O'Reilly, Auto Zone don't have this hose.
Why run PCV?
I don't run one on my Model "A", but on the boat, I prefer crankcase fumes to be returned to combustion chamber to be burned .

NAPA has PCV hose.

Where does one find a new hose shaped like this one off my '72 Skier?
