The best way to check for vacuum leaks is to put a vacuum gauge on
it. The simple combination vacuum/fuel pressure gauges work well and
are fairly cheap. Make sure you choose a vacuum line that is directly
seeing intake manifold vacuum. Many of the vacuum hoses carry
modulated vacuum instead of full manifold vacuum. Choose a line
running to the intake manifold and not some vacuum switch. Good
luck. Al

The other guy mentions using a vacuum gauge, which will work.

If you can get the engine to idle, simply spraying the hose with carb
cleaner will tell you quickly if there is a leak.
The vacuum in the hose will suck in the carb cleaner, causing the engine
to speed up.

If I were you I would just replace the vacuum hoses.
It is a cheap fix.
