- Disconnect the negative battery cable to prevent fuel discharge if the key is accidentally turned to the RUN position.
- Loosen the fuel filler cap to relieve fuel tank pressure and do not tighten until service has been completed.
- Fuel system pressure is automatically relieved when the engine is turned OFF. No further action is necessary.
When disconnecting fuel lines, there may still be a small amount of fuel released. Cover the fuel line connection with a shop cloth to collect the fuel, then place the cloth in an approved container.
