Let me ask probably a stupid question, but I can't find the answer. I'm looking to put a nitrous pressure gauge in the cockpit/dash, but would like one that runs a electric sensor with a pressure adapter maybe? Not looking to bring an actual nitrous line inside the cockpit area, so non liquid gauge basically.

 

Google "electric nitrous pressure gauge". Here's one of the results:

Auto Meter 5774 Phantom Electric Nitrous Pressure Gauge - Newegg.com

There is no big issue with using a mechanical gauge in the passenger compartment, as long as you install it correctly. NHRA tech, for example, permits nitrous bottles and plumbing (including mechanical gauges) in the cockpit.

The mechanical gauge will come with a flow restriction orifice, which limits how fast the nitrous can flow into the cockpit, avoiding the first problem, which is a haze of condensation blinding your vision, as the conversion of nitrous from liquid to gas phase absorbs heat and chills the air below the dew point. The restriction orifice mounts in the engine compartment, where you tee the pressure sensor line off the main line. Obviously, you want to run the line with high quality braided S/S teflon tubing, of the proper pressure rating.

I've had an AutoMeter 2-5/8" mechanical nitrous pressure gauge in the center A/C vent of my Formula for 14 years.

thanks, appreciated, i'll look into that
