Product Features and Specifications

The Delphi FG1255 fuel pump module assembly is engineered for standard replacement applications in Subaru Legacy and Outback models. It features an internal strainer inlet type to filter fuel before it reaches the pump, helping to protect the fuel system. The pump operates on a 12.0-volt electrical system and draws an average current of 8 amps. It includes a fuel level sender assembly with resistance values ranging from 2 ohms (full) to 32 ohms (empty), providing accurate fuel level readings. The outlet type is a quick connect with two outlets, each having an outside diameter of 0.375 inches, facilitating straightforward installation and connection to the fuel lines. The pump module does not include a regulator, gasket, or lock ring, so these components should be sourced separately if needed.

Applications and Common Issues Addressed

• Restores proper fuel delivery in Subaru Legacy and Outback fuel systems
• Resolves fuel pump failure symptoms such as engine stalling or no-start conditions
• Addresses inaccurate fuel level readings due to faulty sender assemblies
• Eliminates low fuel pressure issues that cause poor engine performance
• Replaces worn or damaged in-tank fuel pump modules to maintain system reliability

Installation Notes and Tips

When installing the Delphi FG1255 fuel pump module assembly, ensure the vehicle’s fuel tank is properly drained and depressurized to avoid fuel spills. Verify compatibility with the specific Subaru Legacy or Outback model year before installation. Use appropriate tools to disconnect and reconnect the quick connect outlets and blade terminals securely. Since the assembly does not include a gasket or lock ring, inspect existing seals and replace them if necessary to prevent leaks. Follow all safety precautions when working with fuel system components.
