Stock coolant to EGR spacer hose routing

[1991CO]

I'm in the process of putting a 91 5.0 back together, it was all jacked up when I got it from previous owner doing hack job mods. It had a GT40 intake and I just put the stock manifolds back on. There are no hoses running from the lower intake to the EGR spacer (capped off by previous owner). So now I still have the nipple on the passenger side rear of the lower intake. I'm assuming there needs to be a hose running from this nipple to the EGR spacer? And then, another hose from the other side of the EGR to somewhere? There is a capped off fitting on the hard line (that runs to the firewall), is this where the coolant returns from the EGR spacer? A diagram or thorough explanation would be really helpful. Also if anyone knows the hose sizes for this that would be excellent.

I know I could probably just cap the nipple but I'm trying to get this car back to completely stock for the time being.

Thanks for any help/advice

I beleive it's 1/4" ID line. It runs from the nipple on the hard line, to the front of the EGR spacer, then from the back of the spacer, to the nipple on the lower intake at the rear.
