Detailed Description

Delphi FP10560 is a fuel injection pressure regulator engineered for select BMW 528i models from 1979 through 1981. The unit uses a threaded inlet and outlet, a single inlet and outlet port, and a metal body to match the demands of fuel system operation. With a 36 psi system pressure rating, it is suited for maintaining the fuel pressure level required by the injection system.

Delphi draws on OE experience and supplier knowledge developed over decades of original equipment service. That background is reflected in the FP10560’s application-focused design and fuel system specifications. This part cross-references 21860 and 13531263782 for the same application. The Delphi FP10560 is a direct-fit option for BMW 528i fuel injection pressure regulator replacement when the confirmed vehicle match is 1979-1981 BMW 528i.

Common Issues It May Address

• Fuel pressure that is too high or too low for the injection system
• Hard starting caused by unstable fuel delivery
• Rough idle related to inconsistent regulator performance
• Fuel mixture problems tied to pressure control faults
• Fuel system drivability concerns on BMW 528i models

Installation Notes and Tips

Verify the inlet and outlet thread sizes before installation and confirm the clamp-style mounting location matches the original regulator. Because this unit is non-adjustable and has no gauge port, system verification should be performed with the correct fuel pressure testing procedure after installation. Use the confirmed fitment data for 1979-1981 BMW 528i, N/A, and compare the original part number when replacing an existing regulator.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and technical knowledge developed through long-term original equipment supply relationships. The FP10560 reflects that background with application-specific construction and fuel pressure specifications for select BMW 528i models.
