Product Details

Delphi FP10457 is engineered for fuel injection systems that require stable pressure regulation at 39 psi. The regulator uses a 12.0 mm push-in inlet and a 6.0 mm hose outlet, with one inlet and one outlet for straightforward routing in the fuel delivery system. Its metal construction supports consistent performance in a demanding underhood environment. Delphi draws on OE heritage and supplier experience with major automakers, and that background is reflected in the design of this FP10457 fuel injection pressure regulator.

This part cross-references Gates 24038 for the same application.

Common Symptoms It Can Address

  • Fuel pressure that is too high or too low
  • Hard starting related to unstable fuel delivery
  • Rough idle caused by inconsistent injector pressure
  • Fuel smell or rich-running conditions from pressure control issues
  • Poor throttle response tied to fuel system regulation problems

Installation Notes

Verify the inlet and outlet sizes before installation and confirm the regulator matches the vehicle’s fuel system pressure requirement. This Delphi FP10457 uses a bolt mount, so inspect the mounting point and fuel line condition before service. For 1985-1987 Toyota Corolla fuel pressure regulator replacement, confirm the original regulator style and connection type against the vehicle before installation.

Quality Assurance

Delphi builds this part using OE experience developed through long-term supplier relationships with major automakers. The FP10457 is made to meet the needs of fuel injection pressure regulation in the specified Toyota Corolla applications.
