Whoever says they did this without removing the brake booster must have a magic trick up their sleeve or care little for the safe replacement of this critical component, which stands out as yet another example of not so brilliant engineering by the manufacturer.

Interestingly, the PET for the '85 models show that two connecting pieces ( 477 209 169 and 477 209 161) were added to the hard lines approximately under the driver's seat in order to correct this glaring engineering mistake.

I am reasonably certain the seller of this kit (http://www.rennbay.com/fuel-hose-rep...7a8b4386cdbe87) is aware of this predicament and perhaps chose not to mention it in their installation instructions, to make it seem like an easy 15 minute job.

While you're at it, and having to remove the brake master cylinder and lines from the booster, it is an excellent time to replace the brake fluid in the system.
