Workshop Hints
Before any service work is performed on any fuel system related component, always adhere to the following
- Observe relevant safety legislation pertaining to your area.
- Ensure adequate ventilation.
- Use exhaust extraction system where applicable (alleviate fumes).
- DO NOT OPERATE THE FUEL PUMP unless it is properly installed in the fuel tank and is submersed in the fuel (fuel lubricates the pump).
- DO NOT SMOKE while performing fuel system repairs.
- Always wear adequate protective clothing including eye protection.
- Use caution when working around a HOT engine compartment.
- During fuel system repairs that involve "sealing rings", always replace them with new copper sealing rings only.
- BMW does not recommend any UNAUTHORIZED MODIFICATIONS to the fuel system. The fuel system are designed to comply with strict federal safety and emissions regulations. In the concern of product liability, it is unauthorized to sell or perform modifications to customer vehicles, particularly in safety related areas.
- Always consult the REPAIR INSTRUCTIONS on the specific model you are working on before attempting a repair.
