hi im fitting a boost gauge to my 1.8t and just want some pics of where you guys have fitted the tubing in the engine bay as i dont want to mess it up cheers

 

Just splice into the vacuum line going from the intake manifold to the FPR or DV. The FPR line makes more sense as its closer to the firewall.

 

This ^ is a very common location. Just get a vacuum T-fitting from a local auto parts store (they usually come in a pack) and use one that's 1/8" or 3/16".

There is a check valve on the line going to the brake master cylinder, and this check valve has a port sticking out the side that was capped off on my car. At one point that cap was slightly damaged and was causing a boost leak so now my boost gauge line is connected to that little port, and a straight silicone line connects the FPR to intake manifold.

 

right by the coolant resevior are those black...diverters? in the vac lines. i was playing with them and actually you can cut the end off the "t" of it to get vaccum. VERY clean and its slick lookin. Dont have a digi camera lol otherwise ide show ya.

 

Are they round and about 3/4"-1" in diameter? If so those are check valves. The diverter valve is located in/near the turbo inlet pipe, on the passenger side.

 

yeah it must be those little check valves. In all seriousness, it works slick and the tubing looks almost factory. combined with the gauge in the blocked heater vent, its niice lol
