PCV coolant hose part numbers

[BigCars4Ever]

I have been searching for the PCV coolant hose part numbers with no luck. Anyone have a line on them? 20 years and 140K miles so it may be time to change any lines with coolant running through them.

I have the FoMoCo Snap-On parts catalog. Which hose is this? I'll get you the number.

It's the two coolant hoses that heat the pcv valve in the intake. they are like 1/4" diameter and one goes to the crossover tube and one goes back to the firewall.

Those were the last part numbers before supersession. My catalog won't show a diagram.

Those were the last part numbers before supersession. My catalog won't show a diagram. Do the superseded parts fit or are they a jury-rigged fix?
