OK reservoir hoses replaced...
I believe you definitely need to replace the oetiker's with worm/band clamps. I can see no reason that BMW uses the oetiker's other than to cause you to spend a lot of money in their shop if you are ever stuck on the side of the road. Without my roto-zip and an abrasive blade, I would not have gotten the one at the pump off. And if stuck on the side of the road, I estimate I would have had to get a tow job to a shop to replace the hose at about $500?
Without using the BMW PS line
tool I believe I would have been fighting to get the high pressure line off for hours.
As it was, with the tool, it only took about 30 seconds. The odd thing was that after putting the new high pressure hose in, I tried to remove it again in order to reposition the low pressure line - nothing doing, once the new line locked on I could not get it back off. So, I bent the hose to move it instead.
Years ago, a BMW dealer told me they wanted to replace all the lines to the tune of $800 for all of them. I spent about $60 for the reservoir hoses and sat on them for years until needed for this job. Saved a good bit of money - thanks to those who contributed to this thread and to the success of this job.
I rate this job: easy - so long as you have the proper tools.
On a side note...
While under the car, I decided to change the motor oil too, as usual I spilled a little on the floor. For this reason, and because I need to replace the pan gasket of my RX7, and because after about forty years of working on my cars on my back, I think it is past time I get a garage lift. Has anyone installed a two post lift? Any reviews?
