Manifold plugs?
Ok guys so I got my delete pulley and Im ready to take my air pump off but I dont want to crimp the tubes to the manifolds incase I ever have to put them back on. Is there a certain kind of plug that I need to use to plug up the manifold holes? I was thinking I could use something like this. Would that work?

If the plug fits, why not? The check valve should prevent exhaust from back flowing if you want to or need to leave the air tubes attached to the manifolds. Those manifold fittings are hard to get off without damage..
Good luck!

That should work. I remember a while back someone did that same thing and i think they were 1/4 inch plugs. Get yourself some penitrating oil, when the engine is cool of course, and let them soak. The air tubes should come off no problem. Good luck!
