  Q: How to service and repair the fuel pressure sensor on Ford Escort?

  A: Service and repair of the fuel pressure sensor requires first disconnecting the ground cable of the battery. Kinds of smoking along with open flame use must be avoided around fuel components because highly flammable fuel mixtures constantly present can cause burns and other injuries. The fuel system maintains high pressure even during engine shut-off so it needs to be reduced through an appropriate procedure. First remove the fuel pressure sensor by unconnecting its electrical connector and vacuum hose while taking out the sensor with the end screws. Examine the O-ring seals before installing fresh replacements when required. Clean Super Premium SAE 5W-30 Motor Oil XO-5W30-QSP or an equivalent that complies with Ford specification WSS-M2C153-G should be used to lubricate new O-ring seals under installation but avoid using silicone grease because it can cause fuel injector blockage. Finish the sensor installation by performing the removal steps in the reverse order.
