Adj. Fuel Pressure Regulator
An adjustable fuel pressure regulator is an easy way to adjust your air/fuel mixture at wide open throttle and help fine tune your fuel trim levels. This 97-98 Corvette regulator is a factory replacement that is held in with one retaining ring and has no fuel line attachments to worry about. Very easy to install and adjust. This product is for fine tuning only. Not intended to make major changes to your mixture due to large injectors, rich idle conditions, etc...where programming may be needed.
