Is there anything wrong with tapping the gauge into the vacuum line running from the bypass valve to the fuel pressure transducer?

My gauge definitely works, got all the way up to 35psi with my floor pump last night but still not seeing boost when driving? Any other ideas?

I did have the boost gauge hooked up. It was tied into the nipple i installed on the manifold.
You can see it here: 32 sec mark(the boost line itself is covered in the wire loom)


Not really sure what your talking about with the DPFE?

Here is a pic. Cant see the nipple, but you can see the boost line running down the fire wall wrapped in wire loom


here are some more:






Hangwire: Edit one of the photos and show me what your talking about. Circle it in red or something.

WTF is this loom? It certainly isnt teeing into the 45 degree fitting. Its coming from the bigger fitting that is further back towards the firewall that was put in one of those bull plug holes. It appears this simply goes into the back of your DPFE. See pics.

Heres the loom


Loom again.


This is where it appears to me its going. Which looks like its connecting to the back of some sensor there(I assume its your DPFE oddly mounted). I don't see where that loom goes along the firewall and into the interior.


Still cant find your boost line in your pictures.

ok, well i cant see the pics on my company computer, but i did view them on my iphone. So.... The loom covered line you are pointing to in pics 1 and 2 IS my boost line. Its covered in wire loom to help protect it from touching the EGR line(or any other hot surface) and melting. I may have swapped out the 45* nipple for the larger straight one.... ? I just dont remember. But that is def my boost line that is tied into the manifold.
The line itself does not run straight back through the fire wall to connect to the gauge. It connects to the sensor(the one you are pointing to in pic 3) that was supplied with the gauges. My boost/vac is electric, therefore the boost line runs to this sensor and the electric signal is sent to the computer for the gauges via the weird plug you were speaking of. Just FYI, but I have these gauges(http://www.autometer.com/cat_gaugeli...&opid=1&szid=2 )

Makes a lot more sense now, mine is mechanical so I was like wtf. You definitely have the boost hose harness going to the 45 degree fitting and your actual boost gauge hose going to the vertical fitting, as clearly seen at :32 of that vid. Either way i'm clear on that now thanks a lot dude. Was about to call you on that one but I was like eh I'll figure it out. That will be my shop's problem anyways now. When I got everything all together my passenger rear injector was leaking from the fuel rail. That and I friggin CRACKED my Power Distribution Box trying to get the bolt off so I could put the intercooler harness wire on there. I couldn't believe it, the f*cking bottom of the box CRACKED off before the bolt gave way. And now my horn doesn't work and my car is locking by itself. All other electronics work though so far, intercooler is pumping, headlights + brights work, turn signals, interior lighting, etc. I said F it and towed it to the shop and told them fix it. Might be quite costly.....

Your build still on hold? I want to see trick flow heads + KB cobra blower on a 2V ASAP.

I was wondering how he had the 2.8 lol.

I WANT THAT ONE!! lol

Tim99GT

lol yea its still on hold. The divorce should be over here shortly(next 2 months or so) and then i can really start spending more time on it. Its just been put on the back burner for now until everything is said and done.

Well like i told you, feel free to call me anytime when you have questions like that. i dont mind at all
