Detailed Description

The Mahle GS33654 is a fuel injection nozzle O-ring kit engineered for vehicles that use upper injector nozzle seals in the fuel delivery system. Fluoroelastomer construction is selected for its resistance to fuel and elevated operating temperatures, helping maintain a consistent seal where injector leakage or hardening seals can affect drivability. This part cross-references FEL-PRO ES 70600 and Toyota 90301-07001 for the same application. Common fitment includes Toyota Camry, Toyota Corolla, Toyota RAV4, Lexus ES300h, and Lexus CT200h applications, along with additional Toyota, Lexus, Mazda, Scion, Pontiac, Chevrolet, and Geo models. Mahle GS33654 is a practical choice for injector service on a wide range of import and domestic platforms.

Common Issues This Part Helps Address

Installation Notes and Tips

Inspect the injector bore and nozzle surfaces before installation, and replace seals only on a clean, dry fuel system. Lightly lubricate the O-rings with a fuel-safe lubricant during assembly to reduce tearing and help the seals seat correctly. Confirm vehicle-specific fitment by year, make, and model before service.
