Glow shift fuel pressure gauge help

[farmboy7.3]

ok i have four glow shift gauges the fuel pressure gauge was working for about 3 1/2 days then just pegged out at 100 psi. i checked my ground and have a complete circuit. when i ohm the wire going back to the gauge with it on the sending unit i have some high ohms when you lift it from the circuit at the sending unit and ohm it it loses around half hopefully it is still reading through the gauge. so my question is what else do i need to check. Pull the sending unit and look for trash? put a known psi value on it and see what it does? I have already emailed glowshift and i am waiting on a reply back.
thanks in advance

Mine did the same thing after a few months. I haven't fixed it yet but I called glow shift and they have some test that you can do. Call them and you'll get it figured out. You'll be on hold for a while tho.
