What are the crucial safety precautions and steps to follow when servicing the fuel rail on Ford Flex?

In the maintenance of the fuel rail, put safety first, that is, do not work with flames and disconnect the battery. Discharge fuel pressure, clean up residues and take off upper intake manifold. Disassemble the fuel parts, change O-ring seals to fuel-resistant, and reassemble all of this, and make sure that everything is torqued and reconnected correctly before replacing the intake manifold.
