vacuum fitting needed for MK 1 caddy diesel

[Blue Haze]

I'm looking for the vacuum fitting going from the vacuum pump to brake servo also has two other ports one goes to the heater controls.  The fitting would be good but if someone has the part no that would be a big help also.  I have not tried a dealer but I doubt they can get it since it is so old.

Should be able to make one out of a couple of tees and some simple hose.  Big diameter for hoses to brake servo and a second tee of smaller line to it.  Give you the two take offs for accessories and still pass vacuum from pump to booster.  NO?

I thought about that, I assume that this is not a ported fitting.  It would be a cleaner look if I could find the right fitting though.

i used a 98 tdi pipe from my vac pump to booster on my kubvan... same booster... if stock... almost same place too...

rubber hose on vac line is bad idea.. what if it sucks shut... so fyi it is not just any hose...

you can use hose to fix a cracked/broken in 2 pipe as the pipe can be on the inside... very small area to suck shut that way..

now westy bunny like you have stock they did use a rubber hose.. very thick walled.. but a jetta same vintage went to plastic hard line..

last fyi.. if a mk3 pipe fits a mk2 should also..

Yup, I've done a few mk2 and mk3 engine swaps to mk1.. and always used whatever booster line was on the vacuum pump. Now the early diesel mk1 stuff was the diaphragm pump, so that puts it higher up i believe.. it should still work though.

The hose to vacuum booster and EGR are hvy walled rubber.  The tubing to the heater controls is hard plastic w/rubber connector to mate the tubing to the fitting off the vacuum fitting.  This fitting has laid against something hot and melted a small hole in it. Brakes, after it sat all night, were not too good until the booster filled back up.  I have glued over the hole for now looks like it will work.  I just thought it would not be difficult to find this fitting but that is not proving to be the case.    Now from a stop I am getting a pretty good puff of blk smoke that I did not have before does this mean that the EGR was not working before with the vacuum leak and it is now?

what egr?? diesels in usa did not get egr till tdi... bu ti have seen a 85 quantium td with egr before.. they wanted gold prices fo rit 15 years ago.. so i let them scrap it vs buy it.. and the yard did crush it cause i refused to pay 1500 for it.. so i watched them flatten it..

This is a German AAZ motor bought from Quality Auto in Chino Hills, Ca.  Not sure of the year though.  Sure looks like an EGR valve.  Might just disconnect it and see what happens.

Can you post a picture of your engine?

Tried to send picture as attachment but file is too big.  Can you tell me how I can send this picture?

Finally after much effort!!!!  Picture of my motor.  "EGR" valve against firewall center.   Maybe this should get ported vacuum not full vacuum off the pump?? 

[ORCoaster]

Shouldn't be any greater or reduced by running off a port.  Pump pulls continously and I have a gauge on mine and it holds real steady at 28 LBS of vacuum until I get on the brakes repeadily.  Like four full pedal stomps.  Don't normally drive that way just trying to figure out what it would take to drop it down to say 20.  Even so it comes back fairly quickly.

Why do I run a vac gauge on my brake booster?  Let's just say I had issues with it fading and I needed to know if it was from lack of vacuum or something else.  Turned out to be the master cylinder but once the gauge was in place I just hated to take it out.

I disconnected the EGR valve completely.  Now the smoke on take off from stop is nearly gone and mtr is more responsive.  This must have orginally been connected some other way than directly to vacuum pump.
