For the hydroboost plumbing I ordered new lines that fit the 04 2500 donor. I ordered a pressure line for my 72 and cut the ends off of it and flared them onto the hydro lines so they would thread into my gear box. $100.00 worth of lines and a couple of flares. I bent up a return line from piece of scrap that will go over the frame rail and to the return at the pump.
