Thanks for the response Peter. I have the hand held vacuum pump doodad, purchased years ago for another reason and never used. The car is a 115.

This is a hand pump that allows you to supply controlled vacuum on demand, and has a handy gauge to detect leaks by watching for bleed-off. Lacking that, the best you can do is to check the condition of all the small rubber connectors on the hard plastic lines, also the condition of the plastic lines themselves. The rubber gets rock hard or soft and smeary, and leaks in either case. Similar sized standard vac line works fine for replacement except for special T or Y fittings, in which case the dealer is the best source. Note that there are often "splices" made of plastic -- these are control orifices and must be re-installed. Do not clean them with a drill, you can cause troubles that way. Trunk lock and gas filler are indeed part of the vacuum lock system, and likely you have a bad actuator for the trunk lock if it doesn't work at all. The vac tanks are in the rear bumper and behind the front left tire under the fender behind a splash sheild. The tank behind the spare tire is the fuel overflow catch tank, I believe. The tranny control (assuming this is a W123 and NOT a W115) is white plastic line, the heat/AC system is green, and the door locks are yellow plastic lines in the engine compartment. Brown line is the supply for the vacuum shutoff on the IP, brown with blue stripe is the actuator line for the cutoff. More advice when you get farther.
