  Q: How to service the fuel pressure sensor safely and effectively on Lincoln LS?

  A: Service of the fuel pressure sensor requires you to disconnect the battery ground cable for safety purposes first. Safe fuel system pressure relief exists as a prerequisite before handling any fuel lines or components to stop hazardous fuel sprays that might cause fires. Before proceeding start by removing the engine appearance cover while checking that the noise suppressor remains on its proper position on the Intake Manifold. First disconnect the electrical connector along with vacuum tube from the fuel pressure sensor followed by removing its mounting bolts. During new sensor installation use a torque of 44 lb-in (5 Nm). Also evaluate the O-ring seal for replacement when needed. Before reinstalling the removal procedure you should apply clean engine oil to the new O-ring seal.
