Fuel System Manual: Fuel Manifold

Product Overview

The fuel manifold system is a crucial component of modern engines, enhancing the efficiency and adaptability of fuel line installations. This feature ensures optimal pressure management within the fuel system and provides a secure and leak-proof connection.

Key Features

• Integrated design within current cylinder heads for enhanced flexibility in installation.
• Marked passages for easy identification: “IN” for the top manifold and “OUT” for the bottom manifold.
• Steel sealing washers ensure a tight seal with torque specifications of 40-45 lb-ft (54-61 Nm).
• Special fitting in the outlet manifold to maintain proper fuel system pressure.

Benefits

• Enhanced installation flexibility with inlet and outlet passages at strategic locations.
• Improved sealing against oil leakage thanks to updated connectors with nylon inserts.
• Elimination of leakage with smooth sealing surfaces and advanced connector design.

Usage Recommendations

• Ensure proper installation by utilizing the appropriate torque specifications and sealing washers.
• Refer to Section 13.2 for precise restriction sizes to maintain correct fuel system pressure.
• Regularly inspect for wear and integrity of seals to prevent fuel or oil leakage.

Additional Information

Earlier designs used external fuel manifolds attached to the cylinder head with various sealing methods, including copper washers and lock nuts. Advances in design have replaced these with a one-piece connector that employs a nylon insert for a foolproof seal. This evolution in design reduces potential leakage points and simplifies assembly.
