The culprit- 81 300sd
The problem- Vacuum is great at the hard line coming off the vacuum pump, I took the brake booster hose off, applied vacuum gauge to the hard line, and received a reading of a strong 23"Hg. When I hooked the booster hose back up, and take a reading from the first tee, or second tee as far as that is concerned, I get a bouncing needle between 0 and 7. Mind this is a brand new booster hose..
I got the same reading with the first vacuum pump.. had an extra one laying around, slapped a rebuild to it, new check valves, seals, etc. put that on the car, and, the same readings. Great pressure at the hard line.. terrible pressure at the tees...

I am at a loss as to what it could be... how can I get great pressure 4 inches in front of a tee, and terrible pressure at the tee?? like i said, brand new booster hose...

any suggestions?!
