the hose is supposed to be sucking at idle.
thats why the gauge should display vacuum.

stupid question, but if the gauge is not reading 0 when the engine is off, it's broke.

 

hmmm..im gonna go mess with it some more and drive it a little..ill let you know what i come up with..

 

allright, i'll check back in the morning

 

im back i think it's the connector screwed in the back of the guage..the connector that came with the 42dd tubing kit..no matter how much you push the hose in or how you mess with it, you can still hear the vac line sucking, and when you can hear it it's not reading any hgs at all...

 

two things, make sure there no kink in the vac line. Secondly does your tube have a farrel at the gauge end of the tube? If so make sure its seated right. I had that problem...

 

I actually fixed it earlier today...by that I mean I went to home depot and got a new tube and it worked just fine...42dd can make the sh8t out ofa dp, but they should double check their odds and ends

 

good thing you fixed it!
