[AT] hydraulic pipe question

[Howard Fleming]

Quick question on pipe suitable for a hydraulic line on a Ford 8N.

I need a short length of pipe to run from the hydraulic test port up to 
the front of the tractor.  The fitting I have to connect to the test 
port accepts 1/4 inch pipe, which I will need to size up to 1/2 inch for 
the coupling.

What type pipe would you all recommend, or would I be better off running 
the whole thing in hydraulic hose, and rigging a heat shield where it 
runs next to the muffler?

The line will be used to run the hydraulic cylinder for a Sauder snow plow.

Thanks,
Howard
