It uses a metal housing, a push-in inlet, and a hose-style outlet to match the original fuel system layout, while the 39 system pressure specification helps maintain the fuel pressure required for proper injector operation. Delphi draws on OE heritage and supplier experience from original equipment development, which is reflected in the fit and function of this replacement part. This part cross-references Dorman OE Solutions 800-142 for the same application. Search terms such as 1986 Mazda 626 fuel injection pressure regulator, 1987 Mazda 626 fuel pressure regulator, and Delphi FP10437 Mazda 626 replacement help identify the correct application quickly.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Part Addresses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFuel pressure that is too high or too low\u003c\/li\u003e\n\u003cli\u003eHard starting caused by unstable fuel delivery\u003c\/li\u003e\n\u003cli\u003eRich or lean running conditions from regulator failure\u003c\/li\u003e\n\u003cli\u003eFuel odor or pressure loss related to a worn regulator\u003c\/li\u003e\n\u003cli\u003eRough idle or hesitation tied to inconsistent injector pressure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify inlet and outlet port sizes before installation: the inlet measures 11.0 mm (0.43 in) and the outlet measures 8.0 mm (0.31 in).
