VS403.V2    Issue: 1 - 09/01/12

The use of a vacuum/pressure gauge is often overlooked when determining 
mechanical condition and carrying out fault diagnosis on internal combustion 
engines. monitoring actual manifold vacuum is invaluable when troubleshooting 
engine faults. This can only be carried out by using a good quality vacuum 
gauge and this, coupled with a hand-operated vacuum pump, also allows static 
testing of all types of vacuum operated systems.
Set out on the following pages are applications that the VS403.V2 vacuum and 
pressure tester kit can be used for, but it must always be remembered that 
these are examples only and reference to manufacturer’s service manuals 
should always be made for correct testing procedures and specifications. 
In addition to this, it is always recommended that additional tests, ie. compres-
sion tests, cylinder leakage tests, ignition timing checks etc. be carried out to 
confirm indications of vacuum/pressure gauge readings.
