Autometer Fuel Pressure Gauge

[12vfleet]

The sender for my 100 psi autometer electrical fuel pressure gauge went bad. I have a tee fitting in my 1/2" AD 150 pressure line right before the injection pump and have the fuel pressure set to 45 psi. Also have a TorkTek OFV060HP on the pump. I know there is a 30 psi snubber they have to go with putting the gauge on the vp44 trucks. Is there another snubber out there that needs to be used? Or was this just a sender failure?
