Detailed Description
Delphi FP10498 is a fuel injection pressure regulator engineered for 1990-1996 Infiniti Q45 applications. It uses a push-in inlet, hose outlet, and bolt mounting layout, with a metal housing and a 44 system pressure specification. Delphi draws on OE heritage and supplier experience from the original equipment side, bringing that application knowledge into this aftermarket replacement part. This part cross-references AP Exhaust 24001 for the same application.
Common Problems It Can Address
- Fuel pressure that is too high or too low at the rail
- Hard starting caused by unstable fuel delivery
- Rough idle or hesitation under acceleration
- Fuel smell or rich-running symptoms tied to pressure regulation issues
- Driveability concerns on Infiniti Q45 fuel injection systems
Installation Notes and Tips
Verify inlet and outlet connection sizes before installation: the inlet measures 11.0 mm and the outlet measures 9.0 mm. Confirm the bolt-mount location and system pressure specification match the original regulator on your Infiniti Q45. Inspect fuel lines, seals, and surrounding components for wear before reassembly, and follow factory service procedures for fuel system depressurization and leak checks.
Quality Assurance
Delphi builds this regulator with OE experience and application knowledge developed through long-term supplier work with major automakers. That background supports consistent fitment and function for the listed Infiniti Q45 model years.
