Fuel hose for coolant line?
This question arises from another thread here:
https://www.ford-trucks.com/forums/1...-manifold.html
most of what i'm reading says using fuel line for coolant should only be done on a temporary basis. I measured my existing hose, it's 5/8" OD & 1/4" ID, which is apparently unavailable at Advance, Auto Zone, O'Reilly and the local Farm Store in Quincy Illinois

no idea ,,, but was wondering how close you can get to size you need,,,, if you could find coolant hose long enough and a hair too small,,, heat too small end in a pan of boiling water then it will expand enough to fit most of the time,,, then get pan of water boiling again and do the other end,,, might work for ya,,,, i used to work for a crop duster and we did hoses this way all the time,,, would not fix cold but after boiling water made it plyable it would go on,,,, did a vacuum line this way just the other day,,, want to guess which one LOL

I think that good fuel line, the kind that can handle fuels with built-in alcohol, should be able to handle ethylene glycol based coolant, and the temperature without problem.
If you are really concerned, replace it with some good fuel line, and given it is under pressure, and there's no 'rib' to keep the line on the fitting pressed in place, use two screw-type clamps on the end visible in the picture.
There was a company my brother worked for in Indpls, Marian Rubber, that had all kinds of hoses and rubber and belts and ????, more than you can believe. They could likely come up with a solution. A similar company local might be able to answer the 'use' question, as could a company such as Gates Rubber.
The fuel line question is likely due to the low pressure of older style, along with the fact that it did not encounter ethanol in normal use. Later fuel line is heavily reinforced, and designed to handle non-friendly liquids.
I would use fuel line rated for the cooling system pressure.
