Hi I know this is a older post. How did the re-conversion go? I am thinking of doing this as well, luckily I was able to get a doner Rover and used the lines to replace the cut ones. How can I test if the lines are sealed and the air ride would get air to stabilize them? I tried running the pump to see if air comes out from the hose but didn't feel any air. Is this a good or bad thing?
