6. Fuel Injector Rail Assembly Replacement

WARNING DO NOT SMOKE OR HAVE AN OPEN FIRE FLAME OR USE ANY DEVICE
THAT CAN MAKE SPARKS. FLAMES OR SPARKS CAN CAUSE FUEL
IGNITION WHICH CAN CAUSE SERIOUS BURNS, INJURY, OR DEATH.
NOTICE: As shown in Figure 7, there are two fuel injector rail assemblies, one on each side of the
engine. Each fuel injector rail assembly is attached to fuel hoses and the fuel injectors
on the three engine cylinders on each side of the engine.
If this fuel injector rail assembly replacement procedure is completed with the engine
installed in the airframe, refer to the airframe manufacturer's instructions for shutting
off the fuel and grounding the aircraft.
A. Fuel Injector Rail Assembly Removal
(1) Remove the harness connector from all three fuel injectors on the affected fuel injector
rail assembly.
(2) Remove the screw and lock nut from each of the two clamps that attach the wiring
harness to the fuel injector rail assembly. Discard the lock nuts.
(3) Move the wiring harness so it does not interfere with fuel injector rail assembly removal.
(4) Put a fuel collection container under the side of the engine where the fuel injector rail
assembly (Figure 7) is to be removed.
