One of the lines that comes off the top of the intake manifold right behind the trottle body should be good. I forgot what all the stock vacuum hoses look like and where they go......

yeah i was looking at the vacuum line at one of the post in here but i wasnt sure if i could hook it up in a vacuiun line...

and silver are you talking about the 2 hose thats on top of the trotle body?

or the one on the ride of the intake manifold?

cause the one on the side is closer to the firewall...

youre not talking about the two vacuum nipples for the charcole vsv and the egr actuator are you?

if you connect your boost gauge to that you will read 0 psi at idle.

If you had a jdm engine w/ the usdm throttle body could you use the second vacuum line for the boost controller? seeing as it has no destination

i connected it on where these 2 hose cross...

look at interex second picture... on the top left theres 2 hose that cross....

i used the one that connects to the manifold...

is that one good? i seem to run preaty good/read 10 psi wich is what im running although vaccum seems to vary when engine is hot or in warm up mode... lower vaccum on hotter engine visa versa.. is this normal?

also i didnt wanna start a new post but my gas gauge stops reading... it stays in one place... never move down or up when i refil... i change the gauge with the extra gauge that i had but still no good... i even tried to intall my electronic gass gauge but it doesnt read anything....

any1 knows how to fix this? i dont mind if other gauge ont work but the gas gauge is something that i want working as accurate as possible...

is this just wiring problem? or its the sender in the tank?

speaking of the stock boost sensor... does that feed anything other than the stock boost gauge? If that's the case, where is it located, I wanna pull it out

It does nothing but provide a signal for the stock boost gauge.

It's on the driver's side of the engine bay, don't have a pic, but it has a vac line going to it, and it says Boost Pressure Sensor on it (or similar)

about your gas gauge its most likely your fuel sender in your tank. if you get a new one its pretty easy to replace. theres a little cover in the floor in your trunk. I think 6 screws to take off it off and anothr 3 to take the fuel sending unit out and just plugs in. 5-10 minute job. maybe less

Dont mean to hi-jack, but my boost gauge isnt workin. I know the car is boostin, I can hear the wastegate open up, trust me, DDP, I can hear it. hehe. Also, I blew an IC hose off the other day, my 1st one, so I know its boostin, HAHA. So is it the sensor? Should I jus say fuck it and get an aftermarket one?
