  Q: What precautions should be taken when servicing fuel injectors to prevent personal injury and contamination on Lincoln Aviator?

  A: The presence of highly flammable mixtures during fuel injector service requires all workers to stay away from any smoking activities in addition to excluding any lighted tobacco or open flames near fuel-related components to prevent personal injury. The fuel system maintains high pressure after engine shutdown which demands relief before working on any fuel components or fuel lines to prevent injuries. Heavy maintenance of fuel-related components demands that all openings for fuel must be properly sealed with caps or tape or another protective method to defend against contamination until all protective elements are cleared to facilitate installment. Start with removal of the fuel rail before proceeding to remove eight fuel injectors while replacing the O-ring seals with special fuel-resistant ones since regular O-rings need replacement instead of reusability. The installation process ends with new O-rings that received engine oil lubrication according to the reverse order of the removal steps.
