Default One way hose? (pics)

I am having issues finding where this hose goes on my engine. It has two one way valves in it, and it is about two feet long, give or take a couple inches.



Thanks a lot.

That connects to the AIR Pump and to the drivers side of the Intake Manifold.

The spot where I have it blocked off is where it goes to on the manifold. The end with the blue thing closest is the end that connects to the manifold:

EDIT: I corrected myself, connects from opti to manifold.

it actually connects to the bottom of the opti spark and goes to the driver side of the intake manifold. i dont think it has anything to do with the AIR pump

Actually that goes to the vent on the optispark, not the air pump.

It contains a restrictor & check valve to pull air through the distributor.
There should be a second hose to supply filtered air to the opti as well. Forget these lines & you may have problems with your opti.

I LIED!! I was just swapping out the lifters and noticed it was still there, I just things mixed up! The one end connects to the optispark while the other connects to the intake manifold. The end with the blue things closest goes into the manifold

Speaking of lifters, did you find any that looked bad?
