I am putting the hydraulics on a 60" frontier plow. I will need to extend the hoses. Do hoses come with fluid in them? If not, how does the air get bled from them? Also does any thread compound go on threaded fittings? I have 2 pistons each with only one line going to them. I am assuming I can connected them to my SCV to use the stick to control side to side motion. I will forgo the tilt to get this. I am reluctant to get a 3rd function at this point.
