Thread: Fuel Pressure Gauge - Analog + ECU

  1. #1

    Default Fuel Pressure Gauge - Analog + ECU

    First, thank you for the continued assistance as I get up to speed on EFI and Holley's HP ECU. Your support has been invaluable.

    Is it feasible to keep the analog fuel pressure gauge I currently have installed, and also wire fuel pressure to the ECU? I don't have a Digital Dash, but I'd like to monitor/review fuel pressure as part of datalogging activities. Thank you.

    If you mean retain the fuel pressure sending unit for the analog gauge, and install a new Holley EFI 554-102 fuel pressure transducer, then yes. I think monitoring & datalogging fuel pressure is valuable data. If that's not what you mean, then I didn't answer your question.
    May God's grace bless you in the Lord Jesus Christ.

    The existing sending unit for the gauge is mounted to the regulator. Any suggestions on where to mount the second pressure sensor? Thanks.

    Anywhere on the pressure side plumbing. You can use a ¼"-⅜" Street Tee NPT fitting to install the fuel pressure transducer & sending unit into the single port.
