Ended up swapping the Tomei external FPR for a Aeromotive unit... I found it easier to adjust and more reliable all around.. you can kinda see it in the driver side corner by the brake booster.. made sure it was secured proper over there.. FWIW aeromotive has a pressure gauge that has a pin that equalizes pressure inside the gauge to atmosphere to prevent any false low readings on fuel pressure! Very much recommend going with their gauge and regulators.
