Okay, so I'm trying to get little parts of my pre-turbo install done and so now I'm moving on to the gauges. I bought the defi d-gauges and I need to mount the oil. press. and so I figured I'll get the boost in there as well (going into a gauge cluster bezel from autometer).

My question is:

Can I run air/vac to the boost gauge while still NA? I don't want to bust the gauge in the vac region. I'll be running the gauge to the eagle vacuum manifold and then the vac mani to the brake booster line.

Thanks for entertaining this less-than-intelligent question

 

Yes, It will just never go past zero into positive pressure.

 

yeah its fine
