GT Cruiser, no vacuum?

[CSX153]

we installed a boost gauge on my moms car today. and when we started it up, it showed no vac. boost works tho. so we unplugged a few vacuum lines just to check and none felt like they had any vacuum. the bov, wastegate can etc no vac. we also sprayed around with some carb cleaner, couldnt find anything. ideas?

thanks

Could you have possibly hooked the boost gauge up before the throttle body?

its inline with the bov vacuum hose

Tee it in to a hose comming directly off the intake manifold. All the things you mentioned in your original post are solenoid controlled, so they may never see vacuum.

the only two lines are the brake booster and pvc. which would be best, before i start T'ing into the wrong line again.


thanks

I T'd into the brake booster, works like a champ. Make sure to use little hose clamps on the actual brake hose(s) though, cheap insurance against loosing brakes.
