FUEL INJECTOR REPLACEMENT - CONTINUED
Tag fuel lines, wire terminals, and injectors prior to removal to aid in installation.
Disconnect fuel supply hose (1) from elbow fitting (2) at rear of cylinder head (3).
Disconnect fuel return line (4) from elbow fitting (5) at rear of cylinder head (3).
Place fuel lines (1 and 4) in a suitable container to collect drained fuel.
Eye protection must be worn to prevent fuel from getting in eyes during fuel removal.
All fuel must be removed from cylinder head before removing an injector to prevent fuel from entering cyl-
inder and causing hydrostatic lock or washdown.
Apply low air pressure for 20 to 30 seconds into elbow fitting (2) to purge remaining fuel from cylinder head (3).
Perform step 5 through 8 for each injector to be removed.
