I just had the ICP regulator replaced, "FP" was 46psi according to the shop (the first time my baby has ever been in any other shop than my own). I am wanting to do the "blue spring" upgrade, but want to install a FP gauge. What are some suggestions as far as brand, digital, analog, and where to install the sensor.
Connect the gauge to the regulator test port. You need a hose and gauge with a sending unit the hose and gauge are sold separately. gauge type would be your preference with a 100psi reading you can see the test port here Page 30: Fuel Supply System
