I have done my research and have a few questions. I dont want to tap into the FPR line. I want to tap into the vaccum line for the bov. Is the line in the pic the vaccum line for the bov. I have searched and cant find a pic of the bov line. My old car was a 2004 VW jetta and I tapped the vaccum line for the diverter valve. It seemed to work fine.

Just follow the hard line from the bov and see where it goes.

I have to switch mine too. Right now I am into the FPR. Doh!

Pop off a line, results in a lean condition, BOOM.

Itll work fine at the DV line. No worries at the FPR line cause you wont have a boost gauge if that line pops off so youll know right away. I can see your concern though

why risk it, you will get the same reading at the fpr as you will the bov...

Just be safe and get the source at the bov...

Only if you are looking at your guage or have the Defi warning siren like I do. But if you do not have the siren and are just ripping around and not looking at your boost guage then how will you know? Why take a chance?

I am switching mine the day the car comes out of storage. I am just going to run off the BOV line.

I followed the evomoto how-to and that was a mistake.

That is not the FPR line. The FPR line is to the left and can be seen at this link:

+1 for a good picture of which tube from the BOV is the best to tap.

On another note, I saw an interesting write up for a different car, where rather than tapping hose they actually added copper plumbing fixtures to the actual connector and 'hardwired' the sensor into the connector - it looked very neat.

+ 1 I removed mine from the fpr line and put it on the bov line, I just followed the hard line up and put it on the hose from that to the intake manifold.. if no one gets a pic up by tonight I will get one one here for you guys

SO WHAT IS THAT LINE

It will not matter which one of the two FPR or BOV just use the correct size vaccum hose and be kind with the tie raps

I believe that is just another FPR line.

Anxiously awaiting pics as I'm installing my boost gauge tomorrow.

TECH TIP: It is ideal to connect to a vacuum hose that goes directly to the intake manifold whenever a vacuum/pressure source is needed. Some hoses connected to solenoids or the throttle body may not read pressure all the time (or at all) and some may not read vacuum. Using any hoses with those characteristics will obviously give you very inaccurate readings...or none at all. The particular hose from the fuel pressure regulator to the bottom of the FPR solenoid reads vacuum and boost 24/7, so it's a prime candidate.


Tie strap all vacuum lines at their connections to ensure they will not blow off under boost.



After your connections are made to the gauge or Control Unit II, start the car and check that the gauge is reading vacuum. Stock Evos will read approximately 16in/Hg (.55 BAR).
