"Ford had about 86,000 ways of managing EGR via vacuum. Browse the vacuum diagrams that Gary has to find some that look like they could have been how your truck was built, and start there. But generally: once the factory vacuum lines are ripped out, there's no going back. If you want it to run better, go FORWARD, to a newer engine with better controls & more-efficient emissions management."
Yes, kind of where I'm at, leaving it as is, that is! I do have my vacuum diagrams to go off of. Thanks.
"I have the EGR on my 300 i inline hooked up through ported vacuum. Like that the EGR valve only operates when I am going down the road and the engine is not under load and is at high vacuum. When the engine gets under a load and the vacuum drops, the EGR valve closes. That is how it was originally routed except I do not have the the temp controlled vacuum valve plumbed in at this time and probably will leave it like that as it is working just fine and my engine is happy."
I do have a note to try the ported vacuum when the weather is better and I have time. Good to hear yours is working. Thanks.
