I bought a vacuum hose kit from 928 motorsports and received a CD that was suppose to have the instructions on it but there isn't one on there. Also my kit is also missing the T fittings does anyone know what size T fittings I will need to complete my kit? Does anyone have a diagram of the vacuum hose routing for a 1985 Porsche 928 S 32V engine?

Thanks

I also bought the vac line kit and I simply recieved the silicon hoses. I don't think the rubber elbows and 4 and 5 way connectors are included. You can buy those seperately. As far as diagrams this was the best I was able to find.

There should be a diagram attached to the unside of the hood, in the small part. It is also reproduced in the WSM (here's a link to an online version: http://www.cannell.co.uk/928_Worksho...0w%20Links.pdf). Also, there have been postings here, just do a thread search. Make sure you get the right year for your diagram.

I should have documented the inner diameters of the t-fittings that I used, but I found suitable sizes to fit the hard plastic lines and the aluminum nipples at Pep Boys. You can use a series of 3-way tees in place of the multiway t-fittings, and I discovered that doing so allowed the vacuum hose junctions under the intake to bend and conform to the limited space better. The multi-way factory tee setup had produced kinks in some of the lines in the confined space. I hope that the kit you purchased consisted of high-temp silicone hose.
