991,981,718 Repair, Replacement of In-hood Washer Hose Assembly

There's a common failure mode for all 991s, 981s, and 718s: The hose line for the windshield washer nozzles breaks at the hood hinge.

Enclosed is a tech doc on how to prevent, replace and/or repair.

Pictures are included at 300+ DPI so they will both printout well and maintain detail when zoomed-in on a screen.

Anyone interested can look it over and provide feedback (possibly through PM) on things that are confusing, in error, etc.

I expect to add a FAQ section at the end based upon Editorial Review.

I just glanced it real quick but wow it appears to be very detailed!

I did this very repair on my Cayman about 3 months ago. I'll review and see if anything sticks out but based on the pics it seems to provide every detail needed.
