just need to know what vacum line i hook inot to get the boost reading, i have already tried the fuel pressure regulator vacum line with no avial, can't seem to find any good how to's for the 01 S40

 

come on, anybody, i know i have seen some of you out there with boost gauges so there has to be someone out there that knows what vacum line to hook into

 

nevermind, found it

 

Sorry man I haven't hook any up.The cars I worked on had them already and never had to mess with the connections.

 

its cool, i had hooked it up to the vacum line directly into the FPR and after i switched it it still didn't work, so i traced the gauge line back and found a kink in it, replced the section and am reading about 8 PSI on it with a spike of 10 when it shifts

 

Cool glad you got it working.

 

Hey Nick,
Got any pics? Where are you mounting your gauge?
