For those of you who have installed a boost gauge in your center vent, what is the best way to route the vac line to the engine compartment?

 

i drilled a small hole in to the lower left corner of the vent. then got knee bolster off and with wire hanger I pulled the hose through the rubber gromets into the engine bay. went around the coolant reservoir and down past the washer fluid reservoir then over to the intake mani.

 

I drilled a hole though the ecu grommet and fed it under the ECU and into the car through the firewall opening - then up under the kneebolster, into the A/C run and out through the vent.

 

me too^^

 

Thanks guys, I'll let you know how it comes out.
