hydraulics hardlines

I want to run hardlines where the lines will be showing(in the bed and the visable cylinders) What size line is used? where can I find it either mail order or what type of shop uses them? what about fittings? any help will be appreciated. thanks

you can really use any size you want to. Most common is 3/8 or 1/2

I purchase my stuff from parker stores, they have everything you need, you cant shop off their website www.parker.com, but you can find a dealer on that site thats near you. They sell both line and fittings.

Heres the pump im hardlined for my new setup im installing.
