Have a fairly old B8200 and one of the metal hydraulic pipes just sprang a leak. I have someone who is going to braise it for me but looking at the four pipes and their condition, this could be the start of an issue. Dealer says pipes for my model are not available (Ser # 50551) and not having much luck online with any thing BF300A. Can the metal pipes be replaced with hose or does anyone have a source for replacement metal lines.
