nitrous and fuel gauges in the cockpit pillar pod

do they have to be electrical gauges

 

Generlaly most go with electrical due to the legal restrictions with dealing with a mechanical cockpit guage.

i got the square nitrous and fuel pressure gauges. VERY nice peices. i need to straighten mine out a bit, but heres a quick pic i snapped earlier today.

 

Nitrous pressure can be mechanical, with no risk. It requires the use of a restriction orifice fitting at the location you tap into the main nitrous line. That way, even with a failure of the gauge or a line inside the cockpit, the flow of nitrous into the cockpit will be restricted.

Fuel pressure can be mechanical, as long as you use the correct high pressure "isolator". Having said that, I would suggest that you stay as far away as possible from using the isolators, because they have a very poor record. I had one fail and allow fuel into the line inside the cockpit. By the time you buy the AutoMeter isolator ($100+), the gauge and the braided SS hoses, it will cost you as much or more than a good electrical guage.

 

Not sure if your still checking this thread but follow what injuneer said. I spend the extra money on an elec fuel press gauge and bought the mechanical n20 press. Im spending about 50 on the adaptors, one for the bottle for the n20 press along with the -4an hose, and the adaptor for the shrader to run the gauge and the line to the n2o solenoid
