thanks for all your input, it is apprecaited.

the vacuum guage measures vacuum. a good running engine will have 17-21 inches of vacuum. the hoses develop cracks. this then causes the vacuum to decrease. by placing the guage in series of the vacuum line then pinch the side that goes to the intake manifold you will see if the vacuum holds or drops to zero.
I guess with your explaination of how you checked for vacuum leaks you are not instructed as to the proceedure.
then you would check for any intake gasket/cracks in the intake etc.
with this test you watch the vacuum guage for changes as you use a propane touch not lighted but with a hose on the touch end and with some propane gas coming out the end of the hose if you pass this over a leak the vacuum gauge will react. you can test this with creating a leak using a vacuum line by making a leak and observe how it will change the vacuum.
some have stated I checked for vacuum leaks . I did not hear anything leaking . this is also not the correct method.
what also is funny when they say , I checked the fuel pressure it squirts really good !
