How do I? I get a schematic of the vacuum lines ( either online or in a repair manual, such as Haynes or Chiltons). You need a good work light, some are hard to find. Go along and check each line according to the schematic. To trace a leak from a vacuum line, it is recommended to change all lines. You can get a package of assorted vacuum lines at VIP for cheap, they also sell the T's and splitters. To check a line for a leak, if it is not obvious with the vehicle running. Check one line at a time. Take one line off, but your finger on one end to block it and blow into the other end. Put it back on before checking the next.

You can find a vacuum diagram for a 1991 Ford Bronco 351 Windsor in a Chilton repair manual if the Haynes manual does not have it. You can also check with local auto stores.

The vacuum hoses are very important in a 1991 Beretta. Without the vacuum lines, the engine will not run properly, and the power brakes will not function.

Some parts, yes. Some parts will have changed between the model years, however.

They lead out under the hood you will see them on the upper passenger side in the engine compartment. I am sure you can follow them from there. If memory serves they run from the engine to the water pump.

Best when one starts leaking, to replace them all at the same time. You might spend more in materials trying to repair it than if you just bought new lines.

If it's like a 92 bird, then the 3 main vacuum lines are located between the Air Filter hose and the throttle body. There is a little Plenum that has the IDLE Air Control motor on one end and a rubber connector coming out of the side of it with 3 rubber hoses in it. any other vacuum hose lines from there are located under the big intake plenum (the big aluminum cover in the middle that has "3.1 Liter V6" written on it.

Did this b/4I have a 94 wrangler with the vacuum switch on the transfer. It shouldn't be any different for your jeep. The vacuum switch cost about $20 or less. Just get a big socket or wrench to remove and replace AND BE ABSOLUTELY CERTAIN OF THE VACUUM LINE ORDER/PLACEMENT. In fact, the way I did this was to use a huge socket wrench to break the threads loose after marking corresponding vacuum lines and nipples. If this doesn't do it, inspect the vacuum lines going to the switch. If you do the vacuum lines check and all is good check the shifting fork, mine brokeon me. It cost 5 dollars at a junk yard.

The doors on most Mercedes in the 1990's operate by air pressure caused from a vacuum pump. If you have no suction, first begin checking the air/vacuum lines themselves for leaks. If this does not work, consider taking it to your local mechanic or dealer for pump replacement.
