Not really much to it.i don't do oil,,not enough around here. But tell me about the instrument.
Not really much to it.
A kit containing a 2-inch compound gauge that tops out at 150 psig and connects with a short 1/4" flare flexible hose along a few different sizes of straight and angled fittings that screw into the fuel units, such as a 1/4" flare X 1/8" MIP, etc…
I also keep an 18" piece of clear vinyl hose in the kit for bleeding air out of the fuel units into a container as well as a nozzle supply tube, so I can also connect right to the outlet on the oil valve solenoid.
Which model/brand kit are you using DVR?The kit I have goes to 400psi, you want to read the most common pressures close to midscale for accuracy.

The larger commercial stuff I've worked on in the past that you could back a truck into and used the Delta FireEye system, would operate at 150 psig line pressure, but the resi stuff I do now is normally only 100 psig max.
