  Q: What precautions should be taken when servicing the fuel pressure regulator on Mercury Villager?

  A: It is essential to stay away from hot tobacco products and flames while serving the fuel pressure regulator since the system contains highly flammable mixtures that pose a risk for personal injury. Under all circumstances the fuel system maintains its high pressure status thus the fuel pressure needs to be released prior to disconnecting fuel lines or components. The fuel pressure relief should begin before disconnecting the battery cable and vacuum line from the manifold. The two screws holding the pressure regulator need to be removed while you must disconnect the rubber fuel line from the regulator before taking out the regulator itself. The process to install the new regulator requires following the opposite steps of removal procedures.
