I was able to get the problem sorted out. Pin hole in the lock(Yel/red) vac line at the RH side where the vac lines transit from the door pillar area to the floor board area. The hole was right at the area of where the clamp holds the bundle of lines to the panel at the turn-up point. I went ahead and got good use out of the vac pump I bought and tested door, fuel, trunk lock system components, seat back latch, vacuum resivoir, and fuel shutoff solenoid. Also found the fuel door (unlock side) actuator leaking as well.

Vac Pump read 22in. merc. (pump to brake booster only) and approx. 6.5 in. merc. with all branches of vac system connected and vac gauge teed in. Is 6.5 a good number? Car seems to be happy with that amount of vacuum.

Thanks again for the help!
