I am going to be adding some gauge on a triple pod and was trying to decide what to monitor on the third gauge. 1 and 2 are Pyrometer and fuel pressure, but I just can't decide on the 3rd one. I'm thinking of getting a Volt meter, since when I fire the truck up in the morning I like to watch my volts so I know when the glow plugs turn off. Also considering either an low oil pressure or coolant pressure gauge.
My 3rd gauge is the low oil pressure gauge. Most others can be monitored via a phone or tablet, and they're important.
I really hope to have a converter going from the gauges to android USB port to an app, so that I have all in a single place.
In addition to what you plan on running already, I run coolant pressure gauge too. Actually I cheated and run BOTH fuel (wheat color for fuel) & coolant (red color for Rotella coolant) in one gauge so really you could monitor everything that you want to. I'm never concerned about low pressure oil because if there is no low pressure oil it will not run anyways since the LPOP feeds the HPOP.
Low oil pressure -- because only takes 5-7 psi to trip the factory idiot gauge -- and that is way too low to protect the bearings
Fuel pressure -- because that is the life blood of the injectors -- fuel is used to "pad" the intensifier piston action
Coolant pressure -- need to know early if a head gasket is starting to leak under high engine load
You can do this with one digital gauge and a rotary selector switch -- not likely you would need to monitor all three at the same time

A more elegant way would be to use a micro controller to cycle thru the gauge inputs -- I have a few Arduino and Raspberry Pi laying around -- even a PIC chip would work
