Hi guys, I have a question about my aem fuel pressure gauge (30-4401). I also have installed a fuel lad pressure regulator with an analog dial gauge under the hood. At idle the analog gauge reads a steady 45psi, while my electronic fuel gauge goes anywhere from 55-30psi at idle. When I’m driving the variance isn’t as much. I have made sure all my hoses are tight and no leaks. When I turn off the car the pressure will drop from 45 to 40 psi. I have contacted aem and sensors and gauges are fine. I have an oil pressure gauge and swapped it with the fuel one and it works normal. Changes the fuel pressure sensor and still gives me fluctuations. Can anyone tell me if this is normal or is there something wrong? Also I do have Buschur’s double pumper with 2 255lph gss340 pumps. Thanks on any advice.
