sprung a leak

[taka21]

i found i was leaking coolant from under the lower intake manifold
upon further research i found that there is a coolant line that runs from the front water bridge to the heater core line at the firewall.
my questions are:
does the hard line have an o ring that can just be replaced and seal properly, or will i need a new pipe altogether

second question is can i remove that pipe and just put a freeze plug in its place to seal it up for good (if i decide to go that route)

thanks
