I had replacements made for all 4 hoses on my Teleflex hydraulic steering. The boat is a Formosa 51. All the hoses had "aneurysms" and I figured it was only a matter of time before failure. Now I am trying to figure out how to bleed the air out of the lines and rams. I can't figure out how to do it since both rams are dual action. If anyone has experience/advice it would be appreciated.
