I am preparing to install my own WVO tank and want to do the hose within a hose to get the coolant to and from the tank plus it will make for a cleaner install (in my opinion)

What do you guys use for the outer and inner hoses as well as unions and compression fittings?

thanks in advance

I use 5/8" heater hose on the outside and 3/8" PEX for the inner fuel line.
Check the www at the bottom of my posts to see my fuel line setup.

still using the pex tubing? where can i buy some?

Almost any hardware store carries it.
I find it at both Fleet Farm and Menards.
