Ive got a 68 plymouth fury vip. Just rebuilt the motor started it up and noticed antifreeze coming out of this hose. Looked through previous pictures of the bay and never had a hose going to this could someone tell me what this is and why my coolant is coming out of it? Just behind the passenger side head coming out of the firewall.

Well regardless, that coolant looks like it’s dribbling from the heater box unless you can see otherwise.

Bypass the box by short circuiting the heater hose and see if it stops.
 
Remove hoses from nipples and "short circuit" them. I've made simple u-tubes of soldered copper pipe and two elbows for a tidy solution. Or just loop the hose. Don't kink it.

Suck out all the coolant from one of the nipples with a wet/dry vac, otherwise it will leak and dribble forever. Forever. Come to think of it, suck from one nipple then the other just in case that works better.

Then begin the hard work of learning about heater core replacement, which is REALLY hard work. That is why you see a lot of permanent bypasses of the heater hoses on these cars....heater core failures due to internal corrosion are common on 58 year old cars. And the inside of the box will be disgusting should you remove it and get it open.

IF you have a/c, there are 2 rubber hoses that connect the heater core to the ''h" pipe inside the heater box...these may be leaking and not the core itself but the whole box needs to come out to fix them...there is vent housing at the bottom of the box that 2 air distribution hoses come off of...3 screws hold this piece on and by removing it you may be able to see the hoses and verify what's going on...Trace 300's pic shows a later model core that doesn't use the "h'' pipe
 
you could hook a hose to one of those nipples and flush the heater core out and/or get a vacuum gauge (mity vac) hooked up and see if it's leaking or if someone just disconnected it (probably leaking so don't get your hopes too high).
 
That "tube" is the condensate drain tube for the a/c evaporator core. Coolant coming from it means the above-mentioned heater core situation.
