Questions and Answers About Gauges

[MrMarty51]

This is a thread dedicated to questions and answers about gauges, all sorts of gauges related to the monitoring of engine, transmission and drive train on our vehicles.
If anyone has a question, an answer, or a suggestion for gauges then please post them here.

Recently I was wanting to fill a compartment on a three gauge pod that I have setting atop of the dash of My truck.

The gauge to the right is fuel pressure, hooked through the toggle switch to, as suggested by @Will L. , monitor the pre and post fuel pressures of the FFM fuel filtering system by utilizing two pressure sending units.
The center gauge position is for the right rear cylinder head temperature, the hot spot on the 6.5 engine.
The left position I had suggested running a transmission pressure gauge.
Then it was suggested to run turbo pre and post drive pressure gauges, both on one gauge.
I did a search for such a gauge, getting both pressures on one gauge, and all I could find was air pressure gauges in that configuration. The lowest pressures being at 100 PSI, and so I ordered in that gloshift gauge.
Then Our Alaskan member showed Me a boost pressure gauge that is for two turbos, both pressures displayed on one gauge and at 30 PSI, I ordered in that gauge.
Today both gauges arrived.
I did not open the gloshift gauge box, sent them a request to return.
Opened the Hewitt gauge box and turns out the Hewitt gauge is mechanical.
Okay, that should not be a problem in dealing with the exhaust heat.
The electronical gauge requires a four foot coiled run of 1/4 inch copper tube, set up with ferrel fittings to adapt it to pipe threads to screw into the manifold.
IDK if the mechanical gauge will require an additionally longer run for cooling before the plastic tube is attached to the cooling pipe or if the four foot is enough.
And so the plan:
Run eight to ten foot of 3/8ths copper tube, connected through ferrel fittings to pipe adapters and hook the plastic tube to the ends of that tube.
Keeping a watch on the plastic tube in case of a melt down, and if so, then add more copper tube until the plastic no longer melts.
Also watching the back of the gauge for signs of soot from the spent diesel fuel.
Any how thats the plan, and, more pics will come after I get the rest of the supplies and begin to plumb this gauge in.
