Yikes, I'm sorry but I missed your message. As I recall, you are talking about the hard lines that run from the front of the machine to fittings under the seat. I have had this problem 3 times and never had to remove much more than the seat and floor plates. The last time, I cut the lines in half (approx.),and had connecting fittings brazed on the cut ends. I connected the line at both ends and then in the middle. That turns a seemingly impossible job into a 45 min. thing not counting the cutting and brazing. The other 2 times, we twisted, turned and cussed for a couple of hours per day for 3 days until they went in. I recommend the first option
