Warning! Remember that gasoline is highly flammable! When working with fuel system components, observe all accepted fire safety measures. Do not smoke! Do not approach the work area with an open flame or unprotected portable appliance! Do not service the system in rooms equipped with natural gas heating devices equipped with a pilot flame (such as water heaters and clothes dryers). Do not forget that gasoline is a carcinogen, i.e., a substance that promotes the development of cancer! Try to avoid fuel coming into contact with exposed areas of the body, use rubber protective gloves, and in case of accidental contact with fuel, wash your hands thoroughly with warm water and soap. Collect spilled fuel immediately and do not store rags soaked in fuel near open flames. Remember that the fuel system of models equipped with fuel injection is constantly under pressure. Before disconnecting fuel lines, relieve residual pressure in the system. Wear safety glasses when servicing fuel system components. Always keep a Class B fire extinguisher on hand!

3. Remove the mounting bolts/lock ring and remove the regulator assembly from the fuel line.
Installation

1. Replace the pressure regulator O-ring (before installing the new ring, lightly lubricate it with liquid machine oil).
2. Place the pressure regulator on the fuel rail assembly and check for free rotation. If there is any sign of binding, remove the regulator and check for twisted O-ring.
3. Once the regulator is properly installed, align the bolt holes, screw in the mounting bolts and tighten them to the required torque (11 Nm). If so equipped, secure the regulator using the locking ring.
4. Connect the return line and vacuum hose to the regulator.
5. Connect the negative cable to the battery. Pressurize the system and check the system for signs of developing leaks.
