Fuel Gauge Issue
 

I have an ISSPRO EV2 fuel gauge installed and was working fine, put the blue spring upgrade in and the pressure was reading around 64 or 65 psi, for some reason over the past month or so, the damn gauge has continued to show an increase in pressure and is now maxed out at 100 psi. Any ideas of what the problem could be? Bad gauge, clogged line, or something else? Any ideas will be appreciated.
