Information
Fuel Pressure Regulator to Return Line
The Genuine Porsche 93011050902 regulator to return fuel line is an OE fuel system hose for selected Porsche 911 Carrera 3.2L 1984–1989 models. It connects the fuel pressure regulator area to the return fuel circuit, helping maintain correct fuel routing and safe fuel system operation. Ideal for replacing an aged, cracked or leaking original fuel line during fuel system service, engine repair or classic 911 restoration.
Fits:
Porsche 911 Carrera 3.2L 1984 - 1989
Diagram ref no 11
This fuel line is used on selected Porsche 911 Carrera 3.2L fuel injection systems.
What This Part Does / Functions
• Routes excess fuel from the fuel pressure regulator back to the return circuit
• Helps maintain correct fuel system operation
• Supports stable fuel pressure regulation
• Connects into the fuel collection pipe / pressure regulator area
• Helps prevent fuel leaks when the original hose is aged or damaged
• Provides correct OE Porsche shape, routing and connection fitment
• Replaces a cracked, hardened, leaking or deteriorated original fuel line
• Supports reliable and safe operation of the fuel injection system.
Why Replace This Part?
Fuel hoses on classic Porsche 911 models are exposed to heat, fuel pressure, engine vibration and age-related deterioration. Over time, the hose can harden, crack, swell or leak. Because this line is located in the engine fuel system, any sign of fuel seepage should be treated seriously. Replacing it with a Genuine Porsche OE regulator to return fuel line helps restore the correct fuel routing and reduces the risk of fuel leaks in the engine bay.
Common Symptoms of a Faulty Fuel Return Line
• Fuel smell from the engine bay
• Visible fuel seepage around the hose or fittings
• Cracked, hardened or swollen fuel hose
• Dampness near the fuel pressure regulator area
• Fuel staining around the return line connection
• Poor fuel pressure stability if the line is restricted or damaged
• Hose damage found during engine or intake service
• Age-related deterioration on original fuel hoses.
When to Replace This Part
• If the fuel line is cracked, brittle, swollen or leaking
• If fuel smell is present around the engine bay
• During fuel pressure regulator replacement
• During fuel rail, fuel hose or intake manifold service
• When replacing ageing engine bay fuel lines as preventative maintenance
• If the vehicle still has original or unknown-age fuel hoses
• During engine rebuild or recommissioning work
• When restoring the fuel system with Genuine Porsche parts.
Where It Fits on the Car
This line fits in the engine bay fuel injection system. It connects the fuel pressure regulator area to the fuel return line circuit on the Porsche 911 3.2L engine. Correct routing and secure connections are essential because this is a fuel system component. Installation should be carried out carefully, with the system checked for leaks before the vehicle is driven.
