I'm sorry for the late reply, I don't always check in very often.
the time it took... hmmm
maybe about 30-45 min to remove the old hoses (had to remember how we got the back section out).
Once the lines are out, maybe another 30-45 minutes to cut the hard lines (aluminum so they cut easy) and attach the hard line adapters.
Installing the ends was easy enough, took probably about 20 minutes (easier to install than remove).
Measuring and cutting the SS hose, installing the hose ends and installation into the car took maybe an hour. I had trouble getting the hose on one of the 45* hose ends, just couldn't get the nut threaded on.
Total time about 2 hour moving fast and knowing what you doing, 3 hours if it's your first time or get hung up anywhere. This was my first time working with AN fittings but they aren't bad at all. I also tend to move a bit slower and take my time.
Also, as an update...
After putting oil in and running the car I noticed oil coming out of the rear section hard line adapters. Due to limited room I just removed the lines real quick, put the fittings in the vise and tightened the fittings some more. I must not have tightened the hard line adapters all the way to create a good seal. After that, installed them back into the car and tried again. This time no leaks. So far after 10 weeks and maybe 2,000 miles, no leaks.
