Walker 17155 Fuel Injector Seal Kit

Fuel Injector Seal Kit for Subaru Applications

Walker 17155 is a standard replacement fuel injector seal kit built to restore the sealing interface between the injector, intake manifold, and fuel rail. It uses OE-style O-rings, grommets, insulators, and seals made for high heat, fuel exposure, and long-term engine vibration.

Compatible with 1992-1998 Subaru Legacy, 1993-1998 Subaru Impreza, and 1998 Subaru Forester, this kit supports leak-free injector sealing on common Subaru fuel system service jobs. Walker 17155 is a direct-fit service solution for restoring proper injector sealing performance.

Key Features

• Standard replacement fuel injector seal kit
• OE-style O-ring seal type for injector service
• Built for heat cycling, chemical exposure, and ethanol-blended fuels
• Restores sealing between the fuel injector and intake manifold or fuel rail
• Supports consistent injector atomization and fuel system operation
• Walker 17155 application-specific fitment for Subaru fuel injector repair

Detailed Description

Walker Products fuel injector seal kits are engineered to replace worn sealing components that can harden, shrink, or crack over time. When injector seals lose their ability to hold pressure and vacuum, drivability and fuel delivery can suffer. This kit is designed to meet OE specifications for fit, sealing performance, and durability, using materials selected for repeated thermal cycling and exposure to modern fuels. For Subaru Legacy, Subaru Impreza, and Subaru Forester service, Walker 17155 provides the sealing components needed to restore proper injector function and help maintain emissions compliance.

Common Issues This Kit Helps Address

• Fuel seepage around the injector seal area
• Vacuum leaks at the intake manifold interface
• Hard starting after injector seal wear
• Rough idle and engine misfire conditions
• Reduced fuel economy from poor injector sealing

Installation Notes and Tips

Inspect the injector, rail, and manifold sealing surfaces before installation. Clean all mating areas thoroughly and replace damaged or flattened seals during service. Verify the application by year, make, and model before ordering; Walker 17155 is listed for 1992-1998 Subaru Legacy, 1993-1998 Subaru Impreza, and 1998 Subaru Forester.

Quality Assurance

Walker 17155 is manufactured as a standard replacement part to meet or exceed OE specifications for fit and sealing performance. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
