    Default Holley 554-102 fuel pressure transducer reading 1 to 2 psi.

    Hi. I have a Holley HP with a Holley 554-102 0-100 psi fuel pressure transducer. The fuel pressure on the laptop dashboard shows 1-2 psi while running.This is a new install, 1st startup. Has anyone had this problem? The car runs and drives great, so I don't think it's a fuel delivery problem. Fuel system is a -10 hose to 100 micron filter, Aeromotive A1000 pump, 10 micron filter, -10 hose to the regulator and a -8 return. Thanks.

    Ensure it's correctly selected in the Sensors ICF drop down menu.

    Well, are you sure it's a 100 psi version?

    Just figured out what I did wrong; it's plumbed in on the return side after the regulator. Thanks for replying so quick.
