Boost gauge doesn't work

[kmanxj]

I just bought my PSD it has a boost gauge made by glowshift, It reads with a vacuum hose. It is ran and T'ed into a vacuum line that comes off the Y pipe. The guy i bought it from says that the line from the gauge is to big??? seems weird to me

are you sure its plumbed into a vacuum line? the only vacuum line is the little green line that runs from the intake spider to the intake filter boot.... if its in that spot then yes the boost gauge will not work because there is no pressure their, hence vacuum line! if its in the black rubber line that runs from the spider to the map sensor on the passenger side of the motor where it should be then the gauge is either hooked up wrong or doesnt work. its a glowshift so you can't really expect to much...
