Are you talking about this? Goes from top of coolant reservoir to the upper radiator hose.
bleed line from reservoir to upper radiator hose. --A 211 501 09 25. $30
Part number 110 on the M113 radiator system.







Or this? Goes from bottom of coolant reservoir to the radiator. The following is the revised part.
Filling hose to expansion tank. A211 500 23 72. $99.48
Part number 95 on the M113 radiator system.

If you are changing the hose, replace the coolant reservoir at the same time. By now it is getting brittle and will fail on you. Inexpensive and only takes a few minutes to replace. I've posted a DIY on it.

The plastics on there the tube connects to so if the recovery tank would be point A the part that broke would be point B and thats what broke.

On my m113k the coolant reservoir went crumbly. Luckily its an easy swap
