Description
The factory fuel pressure regulator (FPR) is great for stock to mild tuning, but is not capable of handling significantly increased fuel demands for high horsepower applications. Additionally, the ability to adjust the fuel pressure allows tuners to squeeze just a little more fuel flow out of your injectors, potentially increasing power potential.
The Tomei Fuel Pressure Regulator comes with four ports total:
- Top: 4.5mm Vacuum signal
- Bottom: 1/8 NPT Fuel outlet (to fuel tank)
- Front: 1/8 NPT Fuel inlet (from fuel rails)
- Side:1/8 BSPT fuel pressure sensor port (comes with plug installed).
Two types/sizes are available, depending on your application. Type S is recommended as a factory replacement and slightly increased fuel demands. Type L is recommended for very high HP applications and large fuel needs. Type L shown in our main photo above, type S shown below.
