Name that hose?!? Please help

[GO BILLS Jake]

2002 Sport Trac, 4.0 - previous owner cut this 1/4” ID hose (for some reason) and Auto Zone is not showing a pic.

Starts on the coolant rail, next to trans dip stick and runs 12” forward then a 90 degree to the drivers side and into the second inlet. Both pictured and when I squeeze the upper hose, coolant spits out.

I feel it’s a dealer only but need your help name and identify please. TIA

Here's a pic from my truck where that hose is going. Any appropriately sized and routed, reinforced hose should work fine. You can see the part number in the pic also.

This looks like it might be it...

Thank you! It does, just routes a different way. Appreciate the time taken to help and ordering this evening. Have a great day.

Believe that's the PCV Coolant Loop.
On a 2001 Job2 V6~4.0L~SOHC, it's 5/16" hosed up parallel & operates with 5/8" HeaterCore Coolant loop.
Suspect it's same on your 2002. It runs from a metal Tee (your pic) near the right Valve Cover,
to the PCVHeatExhanger on the right side of the IntakeManifold throat behind the ThrottleBody,
to the PCVValve oxbow on left ValveCover rear,
& back to the HeaterCore loop via a plastic Tee near the FireWall.
I've removed this smaller 5/16" coolant loop on my ExST & the associated Tees,
as it's a "Rube Goldberg" design that doesn't really work & is only a source of potential coolant leaks.
Suspect your PO did a half job of removing this loop & left you a bit of a mess.
If you do restore original PCV Coolant loop,
recommend stainless 5/8~5/16~5/8" barbed Tees (Amazon or Ebay)
& stock 5/8" + 5/16" heater hose from your local AutoParts counter,
instead of overpriced junk plastic OEM parts.

Damn that looks so much cleaner and probably would have made dealing with the thermostat housing much easier. Think I found my next project.
