Correct part number for this hose?
 

I need to replace #53 in the pic below, the AAV hose on an 87. The part number only pulls up through 86 and when I called PP they said it had been superseded but they were not 100% sure which # would be correct. Its got a shape to it so I guess it needs to be the correct hose. Any body know the part # for this piece on an 87?

oops you have to go to pg. 107-20 in the PET its number 53.

Thanks!

Just use a piece of generic heater hose from an auto part store. Thats a hose made for the heater core in a water cooled car. Just get the right diameter, around 5/8" ID.
Or you can spend a little more, go to a hose supply house and get a fancy blue silicone one or whatever.

If you want one with premolded bends go in the back of an auto parts store and look at all the geberic molded heater hoses hanging on the wall or on racks made for certain cars.
You don't have to find one identical, just look for one that has a section you can cut out that would match up with what you are trying to do.
That applies to the premolded crankcase breather hoses on the catch tank next to the oil tank too. They aren't available from Porsche anymore either.

Good deal; so there is not enough boost pressure in there to be an issue? I have had bad luck trying to use non metric hoses in metric applications but this size looks close enough.

Thanks
