- NOTES: Factory fuel pressure sets air/fuel ratio to rich. This regulator allows you to adjust your fuel pressure for a leaner air / fuel ratio. See your service shop manual for working with your fuel regulator. Disconnect your battery and keep a U.L. approved fire extinguisher within reach before installation. Fine tuning on a chassis dyno with a wide band 02 sensor is recommended but not required. Do NOT lean out your air / fuel ratio when used with Nitrous, Superchargers, Or Turbochargers or severe engine damage will occur...these applications require a richer air/fuel ratio to prevent pre-ignition and detonation.
