Alright. I've been working on this for days now and nobody has been able to give me a straight answer. Over the winter, one of my coolant pipes burst underneath the car due to some residual water that didnt drain when I flushed the system before the snowfall. It was on the passenger side. RIGHT next to the gas tank, there are 2 pipes that run along its side. one on the bottom (which is encased in a black foam insulation of somesort) and one on the top that is just bare.
Would I be correct to assume that these two lines, that are on the passenger side of the vehicle, are the Heater Inlet and Heater Outlet pipes? Not HOSES, but PIPES? the ones you need to remove the gas tank support brackets for?
I have looked through the Haynes manual and can't differentiate them. Which pipe is what?
Can someone tell me Which is which, because everyone I have talked to has given me a different answer. I assumed that the bottom was the Inlet, since its job was to carry warm water to the heatercore, but now I'm conflicted becuase: "Why would the other bottom pipe on the other side of the car be insulated as well?".
Whatever the case, Google searches bring up nothing but rubber hoses that go from the pipe to the heatercore.
The insulated pipes are heater and the metal ones above them are A/C lines. The larger metal pipes along rockers are radiator lines.

So... youre telling me that I have a blown A/C tube, then? The A/C has no connection to the coolant system, so why is it spitting out fluid when the car is being filled with water? And the heater core has two lines entering it, so where is the second line coming from if there is only one coolant line? I never noticed a coolant line running from the passenger side of the car to the drivers side...
maybe the leak is actually from the coolant tube and is spilling out from the same, but lower spot in the car by straight coincedince...

There seems to be some confusion here. The two heater core tubes are on one side of the gas tank, and the A/C lines are on the other. When I mounted my battery up front, I ran the cables along the gas tank where the A/C tubes used to be after I tore out the A/C.

Yeah, thats what I thought. Still doesn't solve my problem of knowing which one of those two lines is the inlet and which one is the outlet.
I'm going to have to eat some crow. Passenger side of car -- 2 hoses. one insulated to keep the hot coolant from engine hot on way to heater core. Metal uninsulated line above it is heater return.. Doesn't need insulation. Your leak could be from either of these 2 lines.
Driver side -- A/C lines. One insulated and one not.
Does that sound better? My 86 is on my lift. I'll check it out tomorrow.

Lol thanks for clairifying. Yes, this makes MUCH more sense now. So my OUTLET hose is broken. RIP winter. thanks guys

IIRC they are for the AC compressor. The R12345678 whatever coolant leaves one side as a cold liquid, and enters the other side as a hot gas.
Ohh wait. My bad. The AC lines run drivers side, then cross over the heat shield to the compressor.
