Coolant leaking from hose that connects to throttle body

I have coolant pooling up on top of the head and its leaking from the hose that runs from the head block to to the throttle body, has anyone experienced this leak before? trying to source a new hose but cant find the correct size.

 

I would suggest buying it OEM. It's more expensive, but it's perfectly formed for that purpose and $17 isn't that expensive. The two hoses circled below are the throttle body hoses. It sounds like you're talking about the left one. The P/N is 1628165010. Here's a link to the part https://parts.toyota.com/p/HOSE---WATER-BY-PASS---NO-4/62997558/1628165010.html
