Source for Vacuum Fittings
 

In freshening up my 3.6 motor, I would like to replace most (if not all) of the vacuum hoses and fittings. There is a a large array of elbows, tees, and other fittings that are rubber. Many of them are marked as NLA in the catalogs. And, for those that are available, the costs are extremely high ($7 for a rubber tubing el). There are over a dozen of those 90 degree ells on the motor making the cost for just that small part close to $100!

Is there an outside source for these rubber fittings and plastic tubing that is more reasonable, and available, since many of the Porsche parts are no longer available.

I can't believe that someone has not run into this issue before with all these old engines out there!
