hey , i recently bought a 95 civic dx coupe with a d15b7 and the previous owner install a vacuum gauge but didn't plug the rubber hose with t-fitting , i know there's several vacuum hose but witch one is the best for this application, does anyone know where to plug the t-fitting or have a picture that could help me ???

Any port off of the intake manifold will do fine. But why do you and why would you need this? Is it a boost gauge or just a vacum gauge?

it's just a ebay (x tune) vacuum gauge , i have no idea why the previous owner put that there but i just want to get it working , i try every hose and the only one working is the one from the manifold to the fuel pressure regulator , but the needle barely move , is that normal ???

its possible the gauge is broken, also it will not move much unless you are driving.

when i drive it only move from 8 to 0 and other civic move from 25 to 0 ??? something wrong ??? ok go on youtube and write ''2000 Honda Civic Si hitting VTEC (a wild man driving!!)'' and watch is vacuum gauge working , is mine supposed to work like that ???

usually vacuum gauges are found on turbo cars, because the vacuum goes both ways (positive and negative) depending on if the car is in boost or not. i dont see why you would need it on a stock car. it wont tell you anything useful other than the engine is making vacuum, which it does 100% of the time.

i want to remove that rpm , shift light and vacuum gauge for the JDM look , mine is a DX so basic cluster , SI cluster are pretty nice but how hard they are to installed ??? are they use the same connector or i have to use de SI wiring harness ???

usually the cluster from the same year as your car should plug right in. im not sure about the si, but the ex cluster would work, and that has a tach too im sure.

EX and SI is the same , because in canada the SI is the sohc vtec. so the 92-95 cluster with RPM sould plug right in ?
