STI Adjustable Fuel Pressure Regulator by Perrin Performance
Of the (6) -6 ports on the Adjustable Fuel Pressure Regulator, (4) of these ports are used to connect to your fuel rails with maximum flow in mind. Rated to 1,000+ horsepower worth of fuel flow, this kit works perfectly with stock engines as well as heavily modified engines thanks to the interchangeable orifices. The PERRIN Adjustable Fuel Pressure Regulator is easy to install as it bolts right into the existing threads where the OEM fuel pressure regulator assembly is normally housed. Installation of this kit requires no special tools.
The PERRIN Adjustable Fuel Pressure Regulator can be adjusted from 20 psi to maximum fuel pump capacity. This allows for added fuel delivery to your engine without recalibrating your ECU. Included are three interchangeable orifices for stock fuel pumps, larger drop-in pumps, and fuel systems supporting 1,000+ horsepower. Unlike competitors' fuel pressure regulators, the PERRIN Adjustable Fuel Pressure Regulator has a port located discretely on the bottom of its assembly. This 1/8th NPT threaded port allows for installation of aftermarket fuel pressure sensors and/or gauges.
The PERRIN Adjustable Fuel Pressure Regulator comes with a black anodized finish to make certain your part continues to look good and resist corrosion during its use. For your convenience the ports are labelled according to their proper connections.
