Product Review

The factory fuel pressure regulator (FPR) is great for stock to mild tuning, but it is not capable of increased fuel demands for high horsepower applications. Tuners require more fuel to power their modern engines and Tomei has created 2 new FPRs to meet this need. The Tomei FPR comes with 3 ports on the bottom, and both sides.  The bottom is for the fuel exit (1/8 NPT).  One side is for fuel inlet (1/8 NPT), and the other is for pressure sensor connections (1/8 PT).  The Tomei comes in Type S (Standard sized Diaphragm) and Type L (Larger Sized Diaphragm).

Type S 185001 is recommended as factory replacement and increased fuel demands.
