Egr

Hey guys did the egr delete.

Do I just plug all 4 vacuum hard lines that are under the throttle body?

In the rear I just eliminated the T that had one line going to the BPT Valve. And left the mess of vacuum lines attached to the back of the head.

Upon looking at several diagrams, im thinking about getting rid of that mess, but im keeping my swirl valve.

With that being said, I would just run the vac line from manifold to the right right of the swirl control valve a put a T in to run to the fuel pressure regulator.
Then on the other nipple on the right right of the swirl solenoid, connect that to the nipple on the bottom of the swirl valve.

My question is, what do I do to the single nipple on the left side of the swirl control solenoid? Leave it open? Cap it?

Bottom line I want my swirl valve to function, and looking at diagrams the only 2 small vac lines I would need are for the swirl and fuel p reg.

Or should I just leave all the mess as is, with the eliminated T that originally was hooked up to the BPT valve?

Sorry if this shits confusing.

And to reiterate, do I just cap all 4 hardlines under the throttle body?
