Westac Fuel Pressure Gauge Went South

[ARARAR]

I've had my (Geno's) Westac fuel pressure gauge for about 2 mo. now and today the gauge went south. It's not the sending unit but the gauge. Normally, upon ignition, the gauge tops out @ about 12psi and the zeros out just before I start to crank it. Today, it went to 5psi and stayed there, ignition on or off. I pulled the leads to the gauge and removed it and it still read 5psi; tapped it a few times and it zeroed out, reinstalled it and it did the same thing. Took a drive and it ran as normal @full throttle and the gauge never moved off of 5psi. Has anyone had the same problem?
