New member looking for help

Hi guys. I'm a pretty new member of the Toyotanation, this looks like a great place to get help, so here goes. Can anybody give me a name, or even better, a part number for the coolant hose in the enclosed picture? It is about the diameter of a fuel line. The truck is a 92 4x4 with a 22RE.

Also, is there a rev limiter on this engine?

Thanks in advance for any advice.
