Mine's not a Uflex, but I think I just ran a long hose from the cylinder bleed screws, up to the helm into a clear bottle that I kept above the helm (high point). Another hose from that bottle into the helm fill screw. Keep the bottle topped off so that both hoses are in fluid, The bubbles will escape from the bottle, but none will enter the clear tubing if you keep it topped up enough. Then steer left and right and release the bleed screws as needed. One man operation but it takes some time to work out all the bubbles.
