It helps regulate fuel pressure at the rail or delivery point so the injection system can maintain stable fuel flow under changing engine demand. The regulator’s 44 psi system pressure specification, single inlet, and single outlet configuration make it a focused replacement part for the listed application. This part cross-references Dorman OE Solutions 800-354 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFuel pressure that is too high or too low\u003c\/li\u003e\n\u003cli\u003eRough idle caused by unstable fuel delivery\u003c\/li\u003e\n\u003cli\u003eHard starting related to inconsistent injector pressure\u003c\/li\u003e\n\u003cli\u003eFuel trim issues tied to pressure regulation problems\u003c\/li\u003e\n\u003cli\u003eDriveability concerns in a 1995-1998 Mazda Protege fuel system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify inlet and outlet port sizes, mounting style, and system pressure before installation.
