Detailed Product Overview

Delphi FP10464 is a fuel injection pressure regulator engineered for precise fuel pressure control in select Suzuki Grand Vitara, XL-7, Vitara, Esteem, and Sidekick models, as well as Chevrolet Tracker applications. The regulator uses a metal body, a 0.43 in. (11.0 mm) inlet port, and a 0.24 in. (6.0 mm) outlet port to match the specified fuel system layout. Delphi draws on OE heritage and supplier experience to build aftermarket parts with application-specific fit and function.

This part cross-references Gates 23048 for the same application. The Delphi FP10464 also aligns with common replacement references used in fuel injection service, making it a practical choice when restoring proper fuel pressure control on these vehicles.

Common Problems This Part Can Address

• Fuel pressure that is too high or too low
• Rough idle caused by inconsistent injector fuel supply
• Hard starting related to pressure regulation issues
• Fuel odor or rich-running symptoms from a failing regulator
• Driveability concerns on Suzuki Grand Vitara, XL-7, Vitara, Esteem, Sidekick, and Chevrolet Tracker models

Installation Notes and Tips

Verify the inlet and outlet style, mounting type, and system pressure before installation. Confirm the vehicle application against the listed fitment for 1996-2008 Suzuki and 1999-2004 Chevrolet models, and inspect fuel lines and seals for wear during replacement. Because this regulator is non-adjustable, correct application matching is important for proper operation.

Quality Assurance

Delphi builds this regulator using OE experience and knowledge developed through supplier relationships with major automakers. That background is reflected in the part’s application-specific design and fuel system-focused construction.
