Detailed Description

Delphi FP10409 is a fuel injection pressure regulator engineered for vehicles that require a 44 system pressure specification. It features a metal body, one push-in inlet, one hose outlet, and bolt mounting for a direct replacement style fit in the fuel delivery system. Delphi draws on OE experience and supplier knowledge used by major automakers, bringing that background into this aftermarket part.

This part cross-references Dorman - OE Solutions 800-301 for the same application. It is a strong match for owners searching for a fuel injection pressure regulator for 1998 Chevrolet Tracker, 1992-1998 Suzuki Sidekick, 1996-1998 Suzuki X-90, or 1994-1997 Geo Tracker. The Delphi FP10409 is also a relevant search term for drivers needing a replacement fuel pressure regulator for these fuel-injected compact SUV and utility vehicle platforms.

Common Issues It May Address

• Unstable fuel pressure that affects injector delivery
• Hard starting caused by incorrect fuel pressure regulation
• Rough idle related to fuel system pressure inconsistency
• Fuel pressure loss in aging regulator assemblies
• Driveability problems tied to worn regulator components

Installation Notes and Tips

Verify inlet and outlet port sizes, push-in inlet style, hose outlet style, and bolt-mount location before installation. Confirm the fuel system is specified for 44 system pressure and compare the original regulator layout to the Delphi FP10409. Clean surrounding fuel system connections before removal and inspect hoses and seals for wear during replacement.

Quality Assurance

Delphi builds this regulator using OE-based engineering knowledge developed through long-term supplier experience with major automakers. That OE heritage supports consistent fitment and fuel system performance in the listed applications.
