I am trying to install my mechanical boost gauge today, but I am unsure which vacuum line to tap into. I already have the gauges vacuum line through the firewall, I just am clueless as to what to cut and TEE into...any help would be great and if you have a pic of the line for you...

you guys are aweome and thanks ahead of time

 

i think u can use any vacuum line that goes to the intake manifold.

 

kind of ebarassing, but i seriously dont really know what im looking at as far as vacuum lines etc...

 

Then you should really take it to a shop.

You can probably find a "How To" for it: Here

 

ummm no shop for me. i know how to do the stuff, i just dont know what friggin line to cut into...

 

Take it to someone that knows what they are doing.

Watch & learn.

 

the fuel pressure regulator is NOT a good location, or so i have heard.

 

wow, is it that f***in hard just to say its such and such line off the intake manifold or wherever?

 

anyone???

 

I'm using the FPR line, no problems.

 

FPR Line - its fine

Thats where Mitsu taps in for the MR boost gauge

 

if you use the FPR make sure you zip tie it good!

the easiest place to tap is where the bov line goes into the intake manifold. Just follow your bov line up to the intake and just tap it there. that is where I tapped it for my Defi gauge. No problems and it's very accurate.

 

And he has a MR....uuuhh
I heard one time in Band Camp....

look at the pics on page two, that is where i tapped my defi boost gauge. it's easier than going to the FPR

 

^^ Yep thats a great pic!

Here you go.

I use the vac line from the DV. This is an old pic - but it should be enough for you to figure it all out.
