yesterday I installed my greddy 52mm electronic boost gauge and the needle doesnt move. i turn on the lights and the gauge lights up but i havent been able to get the neddle to show any movement. ive got the TEE connector it came with between my intake manifold vacumme line and the fuel pressure regulator vacumme line. the hose isnt pinched and it does suck air through there. any ideas???

for the gauges wires (power, ground, illumination and 12V switched) i used the same ones that i tapped into for my cd player does this matter??
