Delphi draws on OE supplier experience to build aftermarket parts with the same application knowledge used in original equipment development. This regulator is a practical choice for restoring fuel pressure control on a 1995-1997 Kia Sephia or on select 1989-1994 Mazda MPV, 1990-1993 Mazda B2200, and 1989-1993 Mazda B2600 applications. This part cross-references Standard Ignition (e.g., PR65, PR475) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues It May Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFuel pressure that is outside the specified range\u003c\/li\u003e\n\u003cli\u003eHard starting caused by inconsistent fuel delivery\u003c\/li\u003e\n\u003cli\u003eRough idle related to unstable injector pressure\u003c\/li\u003e\n\u003cli\u003eFuel mixture problems tied to regulator wear\u003c\/li\u003e\n\u003cli\u003eDriveability concerns in aging fuel injection systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm the inlet and outlet sizes before installation: the inlet measures 11.0 mm (0.43 in) and uses a push-in connection, while the outlet measures 8.0 mm (0.31 in) and uses a hose connection. Verify the mounting style and system pressure specification against the vehicle’s fuel system requirements before replacement. Use clean fuel line practices and inspect surrounding hoses and fittings for wear during service.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDelphi builds this regulator with OE heritage and application knowledge developed through long-term supplier experience with major automakers. That background supports consistent fitment and fuel system specification matching for the listed Kia and Mazda vehicles.\u003c\/p\u003e","brand":"Delphi","offers":[{"title":"Default Title","offer_id":43388599861429,"sku":"BBMX-FP10420","price":146.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DE_FP10420_Fro.jpg?v=1774712467","url":"https:\/\/www.partcatalog.com\/products\/delphi-fp10420-fuel-injection-pressure-regulator","provider":"PartCatalog","version":"1.0","type":"link"}
