URO 94411019803 Fuel Injection Pressure Regulator

Fuel Pressure Control for OE-Style Performance

This URO fuel injection pressure regulator is engineered to OE specification to maintain a steady fuel supply across compatible BMW, Porsche, Saab, and Land Rover applications. It is a direct replacement for the original regulator on vehicles such as the Porsche 944 and BMW 528e, helping restore proper fuel pressure control and air-fuel balance.

Part number 94411019803 is built with a steel body, O-ring inlet, and barb outlet for the specified fuel injection system layout. The non-adjustable design and bolt-on mounting style match the original configuration for a straightforward replacement on supported applications.

Key Features

• OE-spec fuel injection pressure regulator for steady fuel delivery
• Steel construction for durable in-system use
• O-ring inlet and barb outlet connection style
• Non-adjustable regulator design
• Bolt-mounted installation layout
• Cross-references Beck/Arnley 158-0239 and Delphi FP10507 for the same application

Detailed Description

The URO 94411019803 fuel injection pressure regulator is a replacement component for fuel systems that require stable pressure at the rail. By maintaining consistent fuel delivery, it supports proper injector operation and helps keep the engine running within the intended air-to-fuel range. This is especially relevant on older BMW 325e, BMW 533i, Porsche 924, Porsche 944, and Land Rover Discovery applications where fuel pressure control is critical to drivability.

Over time, internal diaphragms and springs can stick or wear, which can contribute to lean or rich fuel conditions. Replacing a worn regulator can restore more consistent fuel metering and improve fuel economy on the affected vehicle platform. Part number 94411019803 is also listed among common interchange references used in the same application family.

What It Helps Address

• Hard starting caused by unstable fuel pressure
• Rich or lean fuel burn conditions from a worn regulator
• Fuel pressure loss that affects throttle response
• Poor fuel economy related to incorrect air-fuel ratio
• Driveability issues on aging fuel injection systems

Installation Notes and Tips

Verify the inlet and outlet port sizes, mounting style, and fuel system layout before installation. This regulator uses a bolt mount, one O-ring inlet, and one barb outlet, so the replacement should match the original connection style on the vehicle. Confirm vehicle-specific fitment for the Porsche 944, BMW 528e, and other listed applications before ordering.

For best results, inspect nearby fuel hoses, seals, and connectors during replacement to ensure the fuel system is clean and leak-free after installation.

Quality Assurance

URO backs this fuel injection pressure regulator with a 24-month unlimited mileage warranty. It is engineered to OE specification for the listed applications, including compatible BMW, Porsche, Saab, and Land Rover models.
