What are the crucial safety precautions to follow when servicing the fuel rail on Mercury Mountaineer?

The fuel rail requires mandatory safety measures because of its flammable mixtures so never use smoking or fire nearby and always eliminate fuel system pressure before removing fuel tubes. Perform all work on the evaporative emission system together with all fuel-related components after disconnecting the battery ground cable. The fuel rail requires careful handling to prevent any kind of damage when used as an object for leverage. Your repair process requires covering all liquid and vapor fuel entry points from contamination with protective materials which need removal before component installation. The process starts with emptying fuel system pressure then undoing the battery cable and undoing the spring lock coupling connection. After extracting the intake manifold, proceed to unscrew the fuel supply tube bracket bolt then reassemble it with 8 Nm (71 lb-in) torque. Remove the electrical connections for the six fuel injector units and for both fuel pressure and temperature sensor components together with their vacuum and electrical connections. The correct torque using a torque wrench must be 23 Nm (17 lb-ft) when reinstalling the fuel rail and its attached injectors through the four bolts. Remove each fuel injector unit along with its specific O-ring seals since these fuel-resistant components need to be thrown out; standard O-ring seals will break down when exposed to fuel thus leading to leakage problems. Reinstall the fuel injector O-ring seals by applying engine oil to them before following the reversal steps for insertion.
