Their primary purpose is to seal the high-pressure fuel rail ports during fuel system pressure testing and service. This allows for accurate testing and prevents dirt and contaminants from entering the fuel system.
No, they are specifically designed for BMW CR diesel engines with M15 x 1mm fuel rail threads, such as the N47 2.0L and N57 3.0L engines. They are not compatible with M12 or M14 threaded systems.
You should consult your vehicle's service manual or confirm the specifications of your fuel rail. The product description lists compatible models and engine codes (N47, N57). If your vehicle has M12 or M14 threads, you need a different product.
No, these plugs are service tools designed for sealing the fuel system during testing and maintenance. They are not intended for performance modification or tuning.
These plugs are made in Sheffield, UK, known for its quality engineering and manufacturing standards.
If a plug is lost, it is recommended to purchase a new set to ensure you always have the correct number of plugs for future service requirements. Individual plugs are generally not sold separately.
After use, clean the plugs with a suitable degreaser or solvent to remove any fuel residue. Ensure they are completely dry before storing them to prevent corrosion or contamination.
Verify that your vehicle and engine are listed in the compatibility section. Confirm the fuel rail thread size is indeed M15 x 1mm. If your vehicle uses M12 or M14 threads, you will need a different part number (e.g., Laser Part No. 7668).
Ensure the fuel rail ports are clean and free of debris. Make sure the plugs are correctly threaded and tightened according to the vehicle's service manual specifications. Check the condition of the plugs for any damage.
Double-check that all plugs are fully seated and tightened. Ensure the surrounding work area is kept as clean as possible during the service procedure. These plugs are designed to prevent ingress during normal service but are not a substitute for a clean working environment.
Compatibility: This set is designed for BMW vehicles with M15 x 1mm high-pressure fuel rail threads, specifically compatible with N47 2.0L diesel and N57 3.0L diesel engines. Applicable models include:
*Important Note*: For standard M12 & M14 equipped CRD systems, use Laser Injection Rail Blanking Plugs - CRD, Part No. 7668.
Setup: The plugs are designed for a direct screw-in fit into the designated M15 x 1mm fuel rail ports. Ensure the surrounding area is clean before installation. Hand-tighten the plugs initially, then use appropriate tools as per service manual recommendations for pressure testing applications.
Care: After use, clean the plugs with a degreaser or appropriate solvent to remove any fuel residue. Store them in their original packaging or a clean, dry container to prevent contamination and loss. Inspect for damage before each use.
