Thoroughly clean the area around fuel manifold (6) and relief valve (5).
Remove banjo bolt (1) from banjo connection (3). Remove sealing washer (2) (not shown) and sealing washer (4) (not shown). Use Tooling (A) to cap the banjo connection and plug relief valve (4). Position the assembly of the banjo connection away from fuel manifold (6) and the relief valve.
Use a suitable socket to remove relief valve (5) from fuel manifold (6). Use Tooling (A) to cap the relief valve and plug the fuel manifold.Installation Procedure
Ensure that all adjustments and repairs that are carried out to the fuel system are performed by authorized personnel that have the correct training.Before beginning ANY work on the fuel system, refer to Operation and Maintenance Manual, "General Hazard Information and High-Pressure Fuel Lines" for safety information.Refer to System Operation, Testing and Adjusting, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.
Note: Ensure that all ports on the fuel manifold are capped. Ensure that the fuel manifold is externally clean and free from damage.Note: Do not install a relief valve that has not been plugged. All plugs and caps must be left in place until the fuel lines are about to be installed.
