Im going to put a gauge on to monitor the vacuum from the engine (2.2 eco), is any line better to use than the another? i was looking at the one that connects to the fuel pressure regulator, just dont want to cause any problems. Any help is appreciated, thanks
For my Boost Gauge and BOV, I just went straight off the intake manifold.
I can't remember exactly where the stock intake manifold line runs to, (because I have IC piping and deleted the stock lines), but you can just tee into the line and put your gauge hose there.
follow the vacuum supply line that runs inside to the heater control panel. If I remember rightly it is white in colour and passes close to the clutch pedal and is a hard plastic conduit not like an electrical wire. Just tee into that line for normal manifold vacuum numbers as it an easier hook-up and a short run to your gauge because I did the same thing with proper results.Dave
