I had Princess Auto make up the hydraulic lines. Was half almost a third the price of doing it all in fancy braided line. I Bronze-Welded -6AN fittings to the return at the pump, and I Bronze-Welded a -6AN fitting to the shortened return barb at the Hydroboost so I can run hydraulic lines for return too, for a more aestheticly pleasing spaghetti-collection of hoses. I will be getting the HB return hose shortened 2".
