    With the EZ EFI 2.0, it just allows you to see the system fuel pressure is correct and what the pressure is with the engine running at the handheld - without getting out to look at the pressure gauge. Some folks also don't like to use a mechanical gauge and prefer to just plug the gauge port on the regulator. The electrical sensor is a reliable, and accurate, standard GM pressure sensor.

    With the pressure displayed on the handheld, it makes spotting a line, pump, or filter problem, easier - as you can see what the pressure drop is under load while driving.

    AA, what type and value of cap did you use? I have the new handheld with the old EZ, and it reboots all the time.

    Non-electrolytic, 82 Pico Farad, 50 volt rated or higher. Mine was an old Sprague poly "Orange Drop" type commonly used in tube amplifiers. Silver Mica and ceramic types should also work fine. Depending on the interference frequency, the Farad rating may need adjusting.

    If you have EZ EFI 1.0, its more likely you have a wiring issue picking up interference near the distributor. This can be a vehicle harness getting distributor interference, and may not be the FAST wiring.
