What Safety Precautions Should Be Followed When Servicing the Fuel Pressure Sensor on the Fuel Rail on Mercury Mariner?

Safety precautions must be applied when servicing the fuel rail pressure and temperature sensor because of the presence of flammable mixtures. De-pressurize the fuel system and looseness the components before detaching them, undo the battery ground connection, and sensor connections. Tighten the sensor bolts to 5 Nm, check and re-grease the O-ring seal and recheck.
