Autometer Boost Gauge install

[KairoCross]

Ok i got a dilema!!

I followed a bunch of instructions on the web to
install my boost gauge to replace the factory one
that doesnt work.

The nylon hose is hooked up to a vaccum hose
under the snout but i get nothing on my gauge.

2002 GTP 3800 Series 2 Supercharged

I was told i was supposed to T into a line near the
throttle body

yes you will need to T it into the line. I can take a pic of mine this afternoon and email it to you

[KairoCross]

Yeah if you could give me a picture of where the nylon hose is supposed to
go i would greatly appreciate it

I guess you can follow the line from the fuel pressure regulator to the throttle body. That would be the right place.

Im sorry im really engine retarded lol

I cant seem to find a schimatic or diagram
of the 3800 Series 2 SC engine :S

So i dont know where to begin

There is a vacuum line under the supercharger snout that T's. You need to tap into this line. One side geas to the MAP, other side goes to the Fuel pressure regulator and the Boost sensor.

If your factory boost guage isn't working, and your new guage isn't working, are you sure you have Boost?

you will see a black vacuum line right under the sc snout. follow it to the back of the engine and T into it there. The line is right above the valve cover...you can see mine in the picture

[KairoCross]

So its located on the right spot just more towards the back of the engine.

ill give it a shot tomorrow when im off work

[KairoCross]

Alright through my endevours this is what i come up with,
i more or less put it in the same spot as you but nothing
has changed, its the same as always with nothing happening

[olopezm]

Just to make sure, is the gauge working?

Anything happens when you suck (creating vacuum) on the hose?

Maybe you got a bad one?

[KairoCross]

I dont think it is a bad gauge, i doubt a person back blow
hard enough to get a reading but my friend blew as hard
as he could and you do see the needle go almost to 1 psi

also my gauge just reads 0-35 psi it doesnt read vaccum

Ok, so are you sure your supercharger is boosting?
