Just installed new Fuelab mini fpr and gauge will not register any pressure. I previously had a full-size fuelab and it registered correctly. Either turning on the fuel pump via link or running the car the gauge shows nothing. There is plenty pressure to idle the vehicle (& when loosening the -an fitting at rail) however this is a full build that I’m just getting the car to the tuning phase now and cannot set base fuel pressure. I attached gauge to air compressor to verify its reading correctly and it is. Any help and knowledge would be much appreciated
