What precautions should be taken when servicing fuel injectors to ensure safety and proper installation on Lincoln Navigator?

The presence of highly flammable mixtures in fuel-related components requires that you stay clear of both smoking and lighted tobacco and open flames during fuel injector servicing time to prevent personal injury. After engine shutdown the fuel system maintains high pressure therefore it is fundamentally important to lower pressure before any fuel line disconnection to guarantee safety. The first step involves taking off the supply manifold for fuel injection followed by removing fuel injectors from this component. Visual inspection of the two O-ring seals on each injector should be followed by replacing them with new ones whenever necessary. First lubricate new O-ring seals with engine oil before installing them according to the opposite order of removal to finish the procedure.
