Ensure that all adjustments and repairs that are carried out to the fuel system are performed by authorised personnel that have the correct training.Before begining 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 Systems Operation, Testing and Adjusting Manual, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Turn the fuel supply to the OFF position.
Turn the battery disconnect switch to the OFF position.
Cleanliness is an important factor. Thoroughly clean the exterior of the component before commencing the disassembly procedure. Thoroughly cleaning the exterior of the component will help to prevent dirt from entering the internal mechanism.
