Heres what I have found,

Checked the the vac line feeding the series of valve around the air box, EGR, charge control, and pressure control, major leak here, have not isolated that one yet. I assume that Charge control (boost?) must stay connected and work, the other two can be abandoned, right? The other small dia vac lines, one goes up thru the dash this holds vac, the other line goes to the vac transducer holds vac and the vac control valve on the injection pump leaks. Now is the control valve supposed to hold vac, are any of the ports on the injection pump supposed to hold vac? The line to the trans leaks down slowly, not too bad. I also cheked the ALDA unit I will not hold vac, is this normal?

Vac pump output at idle, reading at the tee on the line to brake booster is 23”hg. Reading at accessory? (small) line, connected directly to the pump, all lines removed. 21”hg. Accessory line with every thing connected 5”hg jumping +/- 2.0 not good!!!

Trans still shifts hard but not as bad as before!!!!

Suggestions on what to do next?
