Generally a good practice to. For one, you'll have air in the system, and you'll want that out of there. Secondly, you'll want to make sure it can hold a vacuum... very easy to forget to tighten down a clamp, install an o-ring, etc.
# Idle speed incorrect # Fuel filter clogged and/or water and impurities in fuel system # Distributor components damp or damged # Fault in the fuel system or sensors # Faulty emissions system components # Faulty or incorrectly gapped spark plugs and/or wires # Vacuum leak at the carburetor/throttle body,intake manifold or vacuum hosses
from the vacuum source in the intake manifold,to various vacuum operated components

A feather falling in a vacuum is not considered as a projectile motion. Gravity, which is absent in a vacuum, is one of the components of projectile motion.
system isolated and the vacuum pump turned off.
guessing that you have one fo the central axle disconnect systems. the transfer case vacuum switch, and the vacuum actuator on the axle are both prone to failures, but easilly replaced. there are numerous aftermarket kits to convert to a manual, cable operated system, adn remove the vacuum components entirely.
Because a diesel engine does not create vacuum and the vacuum pump is necessary to operate things like the vacuum assist brakes and cruise control.
try changing the distributor cap , Faulty emissions system components , Low or uneven cylinder compression pressures , weak or faulty ignition system , ( Vacuum leaks at the throttle body, intake manifold or vacuum hoses . spark plugs incorrectly gapped ? check the spark plug cables..if they're not in a specific order on the distributor its gonna miss fire..check your owners manual to see the timings
