Warning! Remember that gasoline is a highly flammable liquid! Observe all applicable fire safety precautions when working on power system components. Do not smoke or approach the work area with an open flame or an uncovered carrier. Do not service the system in rooms equipped with natural gas-fired, pilot flame-equipped heaters (such as water heaters and clothes dryers). Do not forget that gasoline is one of the carcinogenic substances, i. substances that contribute to the development of cancer - try not to let it get on open areas of the body, use rubber protective gloves, in case of accidental unexpected contact with fuel, wash your hands thoroughly with warm water and soap. Clean up spilled fuel immediately and do not store fuel-soaked rags near open flames. Remember that the fuel injection system of models equipped with fuel injection is constantly under pressure. Relieve any residual pressure in the system before attempting to disconnect fuel lines. Wear safety goggles when servicing power system components. Keep a class B fire extinguisher handy at all times!
1. Locate the fuel pump wiring connector (see Removal and installation of the fuel pump) and disconnect it. Start the engine and wait for it to stop spontaneously. Disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system! On all models, overwrite the radio settings.
2. After removing the filler cap, relieve excess pressure in the fuel tank.
3. Loosen the fuel line fitting on the fuel filter housing and release any residual pressure in the system. On models up to 1996, no. Residual pressure is released by loosening the service bolt screwed into the hollow bolt of the union connection. On later models, the hollow bolt itself is loosened (service is not provided here).
4. You will need two wrenches to release the union. On models equipped with a service bolt, a second wrench is used to keep the hollow bolt from turning. Where the hollow bolt itself is loosened, the second wrench serves to keep the fuel line fitting assembly from turning (see accompanying illustration).
5. Wrap a rag around the fuel filter fitting to catch spilled fuel.
6. While holding the hollow bolt or fuel line connector from turning with the second wrench, slowly loosen the first service / hollow bolt - fuel will begin to ooze through the joint of the assembly. After waiting for the complete release of pressure, unscrew the bolt completely. Remember to replace the service sealing washer/two hollow bolt washers.
7. When you have finished servicing the power system, screw the service/hollow bolt into place and tighten it to the required torque.
