I just blew a water hose thats right under my carburetor and I can't find the right hose to fit it.

Does anyone know what the dimensions of this hose is and where I can get a pre molded one?

 

If memory serves, the hose you mentioned is the one I circled below. I don't know what the dimensions are but you should still be able to get this hose at your local dealer, other online Toyota parts dealers,
or you can find it here at Toyota Parts Overstock. I just used my truck for the search (since it is also a 22R) but you may want to use your year truck to confirm the right part.

It is also probably a good idea to check the rest of the hoses including the 3 radiator hoses and the heater hoses just to be sure.

 

Thanks!

this was the last hose to be replaced out of my radiator hoses, I couldn't find a pre molded hose but I rigged it up with some regullar 5/8 hose from autozone. We'll see how it holds up because its not a perfect fit.
