Is there any way for me to bypass my distributor delay valve? I'll include a picture of my vacuum diagram. I'm hooking up all of my vacuum lines and I realized I'm missing my distributor delay valve. I couldn't get one at the auto parts store and when I found it on eBay it's $40+. It's supposed to have 4 connections on it. What can I do to get around this problem?

It’s only purpose was to not give you vacuum advance until the motor warmed up. You can just run your vacuum line from the distributor to ported or manifold vacuum whichever you prefer.

Would it hurt anything to run it to straight manifold vacuum? Do I need to hook it straight to one of the thermal vacuum switches on the manifold?

I have mine run straight to manifold vacuum. You just need to make sure you are not getting too much advance and that it doesn't ping.
