Gauge question - Boost pressure

[hlb3]

So I want to add a gauge in my cab to monitor my tank pressure for my air suspension. I don't really want to add another pod anywhere, so I was thinking about replacing my current boost gauge with one of these dual pressure monitoring gauges, have one monitor the tank and the other monitor boost.

Example:

I see no reason this shouldn't work, air pressure is air pressure. Can anybody else think of any reason something like this wouldn't work?

Why not!?! Be the Guinea Pig Les!!! :redneck:

I figure I'll try it and see. I found that Viair has a dual needle mechanical gauge for around $30, if it doesn't work out I at least won't be out much.

Well, the experiment worked, it reads the boost pressure just fine. The yellow needle reads the pressure for the air suspension tank and the orange needle reads the boost pressure.

Looks good. I'm glad it is not 120 PSI of boost.
