Since I got the car, this hose has been in bad shape, so I finally got around to replacing it along with the repaint and interior refresh. Found some flexible black rubber hose the right size, A$10/mtr, even got new splash shields. The attachment to the spash shield always seemed a poor way to do it, IMHO, so I got a piece of alloy angle, and mounted the clamp to it - needed a couple of wooden spacers to provide proper clearance, and mounted it to the spare mount hole on the front of the fender stay. I will check in a few months to see if the arm has drooped, and if necessary make a vertical stay down to the bolt at the fender stay outer end - the one that also fixes the spoiler.

I'm looking for sources for the ducting for an 87, any suggestions?

That's a far more sensible mounting arrangement than the OE one. Better quality hose too.

Colin. 89GT.

that is nice hose. It looks like it would take future oil spills much better too.

Yeah and what is with that convoluted design porsche had. Seems like too much hose, I would think it should be allot shorter and more direct, but what do i know.

Ryan,
Shaped like that to stop ingress of water and crap is my guess.

John,
Can you give more info on the hose please?

IIRC the later 928's had an AC temp sensor incorporated into this tubing. May want to check for wiring before going generic.

The sensor is in the tube in the picture. You cut the tube to add the sensor.

Here's a link to the ducting I bought, 2.5" ID.

Click on the store link and look for defroster duct under the category list.

This duct fits nicely on the alternator shroud. It is a tight fit where it passes near the lower A-arm mount- I had to clamp a few wraps' worth of the wall of the duct in some needle-nose vise-grips in order to pull it thru, but it works nicely. Much cheaper than the OEM duct.

We talked about this last week, guys.....:

The hose is same spec diameter as original - there are two common size here IIRC - 2.25" and 2.5" or 57.5mm and ?. Finding it is mostly a matter of trying all the names you can think of with all possible suppliers(engineering, a/c, dust extraction coys etc) until you hit one they understand. Helps a lot if you have a piece of the old one as a sample. I took the bent end part to a local auto parts guy as a sample, and he lost it!
Its quite a tight fit on the fittings, and took some wd40 as a lube to get it on the temp sensor and the alternator shroud, but I reckon thats preferable to loose. I got it a couple of inches onto the alternator shroud, which I dont believe ever had a clip fitted. I bought 2m (6'6") and used about half of it. It threaded through the front of the lower arm mount easily.

What's up with those Ghetto wood shims- I think Henry Ford used those on the Model- A. couldn't find any steel washers?

It wouldn't be a real Porsche if it didn't have some wood in it somewhere!

Panzer9

You're right- I have wood everytime I drive her.

Spacers - had the right size wood handy, a stack of washers is messy to assemble and looks poor(and reminds one of a dismantled tensioner!), and not many people are going to see them...I hope. And its LIGHTER!
Should I paint the whole assembly black or white? I have some matt black....that would match the hose nicely.

Spacers. Good hardware stores have selections of plastic, nylon and aluminum spacers in various thicknesses.
