Detailed Product Overview

The URO 94411019804 fuel injection pressure regulator is a direct replacement for Porsche 944 fuel system service. By regulating fuel pressure at the rail, it helps maintain the air-fuel ratio the engine management system expects. This part number, 94411019804, is intended for 1987-1989 Porsche 944 applications and cross-references Delphi FP10521 for the same application.

Built from steel and configured with one inlet, one outlet, and three total ports, this regulator matches the specified OE-style layout for the Porsche 944. The inlet uses an O-ring seal and the outlet uses a barb connection, supporting a secure fuel system interface.

What It Helps Address

• Unstable fuel pressure at the injection system
• Lean or rich fuel burn caused by a sticking internal diaphragm or spring
• Reduced fuel economy from incorrect fuel delivery
• Clogged or worn regulator performance
• Air-to-fuel ratio imbalance in Porsche 944 fuel injection service

Installation Notes

Verify the inlet and outlet port sizes, mounting style, and vehicle application before installation. This regulator uses a bolt mount and does not include mounting hardware. Confirm the fuel line connection style and inspect surrounding fuel system components for wear or contamination during replacement.
