This is the return water line from the turbo. It's about 2 years old and has been through about 7k miles. As you can see it began spitting coolant out everywhere. Possible that it was just a defective in some way? Or is it more likely that the damage was caused by the heat? There also wasn't much slack in the line and and it made a long 90° turn right after the 90 an fitting. I just dont want to put a similar replacement line and have the same trouble in 2 years. Thanks for any advice/help!
sometimes that wrap is a double edged sword - it resists heat, but once it gets hot it'll act as an insulator and thoroughly "cook" whatever it's covering.

Perhaps that's why the line failed?

Sounds pretty plausible to me. And coolant over time destroys hoses, but 2 years isn't really long. id say replace it with a steel braid.
I looks like they used race fitting hose, on a push-lok fitting, that's a no-no. Replace the line, and both fittings, with race fittings and the appropriate hose. Also, keep the insulator wrap on it, it is absolutely not a double edged swords. On the trophy truck, we dropped trans temp almost 20*F when we put heat shield/sheath over the trans cooler lines where they run by the exhaust.
This is a picture of the entire line. What would be the "appropriate" hose to use? My hose buildings skills aren't quite up to par and would prefer to pay for a worthy line if anyone has the required skills.....

No, it is definitely a double edged sword. The temperature of the fluid inside the tube basically stays the same but the properties of the outer coating material changes over time because of the amplified temperatures collected from the insulation and moisture collected. Insulation tape and wrap works well in a racing application, but when placed over a cloth hose in that location, moisture expansion and superheating will take it's toll.
