I have not done anything about the fittings/hoses so I can't answer that at this point. When the opportunity arises I plan to find a hose shop and take it in with me. I plan to tie in post selector valve and the line is pretty easy access. It has a readily accessible rubber line meeting the steel line. I figure I will cut off a bit of the steel line and just hose clamp the post filter line back on just like it is now.
I have planned on drilling the frame to hold it and something along angle iron is what I had in mind too. I would like to add a stone guard if possible. I have drawn my idea a couple of times and it should be easy with the proper tools. That is where I fall short. I have minimal, and mostly crappy, tools.
