I have searched for hours and can't find somewhere to buy those vacuum "valves" and fittings
Stuff like the little yellow creatures on the lines headed for the pass compartment. Are those valves or filters?
I also need a five headed vacuum connector, the fours are available but not mine.
Much of the system is soaked with oil.
I am ready to put in a new IP shutoff valve, but want to replace the oil soaked components and somehow clean those lines...
Any thoughts, please?

Replace all the straight, 3way (item # D3011-26557) and 4way( item # D3011-15633) fittings that are rubber. The oil will deteriate them. The hard plastic lines, use a can of brake cleaning spray to clean them out. If necessary use a hard wire to reem the line. Allow them to dry and reuse them.
All the fittings can be bought at Fastlane. $2-4 each. The straight fitting is just 3.5mm inner diameter hose.
There are yellow (item # O4040-16683) and blue ( item # O4040-32232) check valves on the vacuum system. Fastlane has those also. A 5way fitting, I have not seen. Usually a 4 way and a 3 way connected will give you the 5 way.
I would also recommend you fix the oil leak first. It is usually the vacuum pump of the Ijection pump shutoff valve. Check the line connections at each of these items to see where the oil is being sucked into the vacuum system from.
Then install inline clear filters in the vacuum lines so you can see any oil in the filter first befre it moves throughout the entire system. Install the filters at the IP shutoff unit and in one of the lines that come off the large black pump to brake booster line. I use small clear lawn mower inline filters.

Thanks, dmorrison.
I sure appreciate your advice.
The main oil leak is under the dash, ignition switch is soaked,
and those big white vacuum boxes.
I hope I can just clean those out with brake fluid, too.

Hi Thevegmyster.


Try www.************************
for all these.

Louis.

www.**************.com

has good manuals on troubleshooting the vacuum system and sells a small kit with the vacuum fittings, hoses, etc. His "Performance Tuning and Repair" guide and the "Vacuum System Toubleshooting" guide are great and address your specific situation in detail. He says you can clean out the clogged vacuum lines with brake or carb cleaner and compressed air.
Another good tip is to use fittings from an automatic in ground sprinkler system which you can get from your local super hardware store. Get the 1/4 inch fittings. They have cheap plugs, angles, splitters etc. Golf tees work great as plugs too. The "yellow and blue thingies" are the check valves and must be ordered from a dealer...
